Glasurit 90 waterborne base?

Brad J.

Oldtimer
I've been doing some repair on a hot rod that used waterborne base. Painted a door and did 3 blends. Took me a while to adjust my blends so they disappeared. Similar but different technique than solvent. It really wanted to hallow around the blend. I don't love it but it doesn't seem to bad.

It doesn't seem to adhere very well to the primer. A chip is very hard to feather back because it just wants to keep chip off the primer. Does this stuff adhere as well as activated solvent base?

I told the owner I wouldn't switch until I have to. He looked at me kinda funny like everyone is supposed to be using it because his car was done California and that is the standard. Just curious if the adhesion is as durable to SPI epoxy as solvent base is.
 
Just at the BASE school, and Glasuirt 90 line is top of the line and they claim it has solvent in the system so you have best of both worlds.The car you are repairing may not be a good repair to start with. I do know if base is not completely dry before clear you will have problems. I would say in my opinion the adhesion should be about the same as solvent base under perfect conditions. Now with that said I am in PA at the MD line we are not under the low VOC law and I still use solvent base coats so not a expert on water. What my jobber salesman told me a few shops have switched back from water to solvent. The majors make it sound like you have to use water and its the greatest thing to come along since the wheel. Lets see what the other people say on here.
 
Brad from everything I hear what you are seeing is normal, we sell a lot of shops that use the water in California and Canada.
If you don't have proper drying system for the water, do give it plenty of time to let the water evaporate or you will be in big trouble when you apply the clear.
 
The funny thing is this color should be so simple to blend. It's gray/green without metallic with the original paint that was used. I had to really work to get a blend that wasn't visible. Well, it's faintly visible to me but I'm only looking at the areas. I've told several people to study the car and they can't see it. That is a good sign. Only reason I did the job was I liked the guy and wanted to help him out as he had it another place that made a mess out of it.

When I removed the masking tape/paper from the back of the door it removed a lot of base off the door. It's all behind the door panel but I'm glad it didn't remove paint in important areas.

I was disapointed with the blending hallows that solvent never would have. If you spray it wet and feather the edge then the wet spot would end up a different color than the faded area. Real pain and the car leaves today so I hope its a long time before I have to mess with water again.

The tech sheet said it needed to be covered in 8 hours so I think everything I did was at least 6 hours in a 75 degree booth before I cleared. Also with winter here 40% humidity really helped dry times.
 
Well, it didn't work out. He pushed it outside and studied like no other customer I've had. I repainted the door yesteray but I'm about done on the job. I'm only willing to lose so much money on a job before It's a freebie. I'd be better to cut my loses and give him the car back. Send it to Cali and let the original guy do it. This will be the first time in 12 years that I couldn't do a blend where the customer wasn't happy.

Funny part is the car was a high end build but the paint wasn't that great. It was good but not great. I missed he would be that picky with me based on the flaws from the orignal job. Completely missed that. He originally told me the lower cowl had a run that needed fixed and he had the original paint. I thought I liked the guy and said ok. Once it came we rolled it in the booth and he started finding more to repair. Then the paint he gave had been watered down by the other shop. I had to leave the lid off the paint for a week and let it thicked back up so I could use it. Been one pain after the other on a job that I really didn't need or have time but here we are. The original shop was nice enough to send more paint but it's slightly off and the owner noticed the difference. I have a tiny bit let of the original to maybe blend the cowl but I'm afraid it might be worse than what I have it and I have no more paint. Think I might just rub the repainted door and give it back. I know when I'm beat.

Went down to our local body shop yesterday afternoon because he uses Envirobase. When I asked him about it he said he was switching back to solvent. Not user friendly and to slow.
 
Brad, it has nothing to do with your skills, I could write a book on the crap I have heard from painters with these types of bases and everything mention in above posts are things I hear weekly.
How about the painter that called me worked in a 4 painter shop that had bought a new Vette and now the shop switch to waterborne and all the painters income is down 25% across the board, so his wife said to sell the Vette as we cannot afford the car payments and he wanted to know if I would buy it.
My opinion it has no place on any collector car and should not be within 50 feet of one, just to be safe.
 
funny, on these vinyl garage doors i paint i have to use a waterborne system from a canadian company. for waterbase its a very good product and different from any other kind of waterbase paint i have ever used BUT its hands down the trickiest thing i have ever sprayed. unbelievably tough to get an even finish and you cant blend anything or you will see it.
 
Thanks guys. It helps to know I'm not the only one. I've sprayed water before on motorcycle stuff and have never had any trouble. I thought it sprayed good. Never tried a blend though.

I rolled the car out yesterday afternoon and had the wife check out the blend. She has a good eye and couldn't see it until I pointed out the exact erea and then she could. I thought it was good enough at any show it would take somebody a long time to catch it. When a car is one display everyone is usually checking out the lines and details of the car and usually never see the flaws. Oh well, I'm doing a blend on the other lower door but I've decided I might not have enough color to blend the cowl and might make it worse. If I can nail the 2 doors then I will bill him for those and eat the cowl.

It will also go into the memory banks of never again.
 
I blended the lower corner of the right door yesterday. Came out good. I can't see it out in the sun. Today I blended the left cowl right in the center area. I think I have it dialed in also. The door match is almost perfect. Some angels it is and some angles it looks slightly different. This was painted with the last of the original paint.

I will post some pics when it's done and see what you think. It might get interesting because I feel that it's as good as it can possibly get. I can't tell where I've been. If you never told a soul then they couldn't find them. I think. I'm going to want to get paid the original bill. Not the 4 days this week that I will eat to redo it, but at least the original job.

I took my Iwata th airbrush with the fan head and dusted so finely that I couldn't hardly tell I was doing anything. This slowly hid the hallow rings. Real handy in a collision shop. This dusting made the clear dirty with nibs, they are all over the repairs. Pictures aren't helpful as they look like two different colors and very shadowy. I'll take some more when it's done.

I will truly know if it's a something for nothing guy if he doesn't like it.

Well, this time he was happy and I was paid. Sucks it was half price pay but something is better than nothing. That waterborne has issues though. I had a small amount of original paint to spray the door with one coat. If it was solvent then it would be a nice blend coat for color. I sprayed the nice blend coat and it was all funky/blotcy and had to spray a 2nd wet coat that killed the rest of my paint. Not totally perfect as it needed another coat but you have to get right in front of it to notice. The owner didn't.

My blends came out really nice. Slight darker fog but almost looks shadowy so nobody will notice but me. Still not as easy or good as solvent. Next time a customer has or wants waterborne I'll just sweep the floor since the profit is about the same.

I won't show the car but heres what I did. Cowl blend from beltline down and sprayed door. Owner still didn't totally love the door to rear quarter match. Front to back angle it looks lighter but straight on and from the back it matches. This was the original paint used on the car. It was all I was going to do. Wasn't gonna try to blend and paint the back of the body. I was done.

Even though I worked for half price in the end I was glad I stuck with it and he was happy. Around here I don't think a bodyshop would've taken the time to please him. He wanted to bring more work but I'm plenty busy right now.

Looks like you got it right on. i do know with some colors in Glasurit 90 line they spray blotchy and need a light drop coat after coverage is achieved and even then looks crappy untill base is completely dry and clear is sprayed. Sorry you lost on this job. I am sticking with solvent base now.
