Another pearl stripe question

Ok,so I have been reading some of you are painting your stripe color first,then taping the stripes off and spraying your basecoat which is less masking and less chance of overspray.

Since I have to use an intercoat to put the pearl (powder form)over my white stripes anyways, should I do it in this order? The issue I see is the overspray of pearl intercoat, the undercoat color is dark gray.

Doing it this way will leave white and pearl intercoat overspray on part of the roof,trunk,hood and cowl. Does it need to be resealed with the dark gray undercoat and does the overspray need to be sanded before topcoat?
 
In your situation it is probably best to spray the main color(blue?) first. Reason being trying to cover the white overspray with the blue will take several more coats, may not get covered, and will leave a fairly large edge to bury. The other option of resealing can work but would probably need a complete reseal or you would have dry edges, and will leave a heavy edge next to the white. Also sealing over fresh base can sometimes cause it to wrinkle. IMO, the best way would be to spray the car blue and clear 3 coats. Then wait a couple days, sand with 400 to 600, spray your stripes and reclear with 3 more coats plus 1 extra over the stripes.
 
Tk is right. Its not about overspray. Its about masking and which color covers best. Typically i would spray the stripe first if i could but if the overall color doesnt cover well then i would do it the other way around. Most good looking blues dont cover well.
 
Ok that's where I was going with this but wanted to ask just to make sure...you never know, there are lots of ways to skin a cat but which is best? Now I know. Thanks guys!
 
the only way I might see speeding it up is to use white for the seal coat so you dont have to worry about color change of the blue around the stripes over the rest of the car.
 
it just tells you that you are going to see a difference if you paint the white first. Yes, dark undercoat will get you one less coat to get to the chip color, but you spray a chip over a white sealer and you might like the blue you get.

Hhmmm, I have had this question on here before. It seemed to be the concensus that if you had good coverage,the undercoat wouldn't matter,just maybe less coats to cover.

I will definitely do some test sprayouts to check this. Thanks
 
If it's a hard to cover blue it might take 6 or more coats though to get coverage if you use a white sealer. A dark gray sealer will work but I'd go with a middle of the road gray sealer. You'll get coverage almost as quick and it will give a slightly more "true" color to the blue (depending on the shade of blue)

Less basecoats is always better. When you start having to spray 5 or more coats to get coverage it can become a problem with both millage and solvent trapping. Plus you may put on 50% more base which will increase the cost of your base by that amount.
 
The color is "Hyper blue" "Kinetic blue" "Blue me away". Three names,one paint code. I guess GM couldn't decide what to call it. Anyone ever sprayed it?

My guess is your sprayout (black to white card) will take 8 coats to be all one color, sprayed like you would on the car. Sprayed over white or light gray, you run the risk of not getting as much on the bottoms of the rockers, fenders, and 1/4's and being see through. Complete coverage is a pain, perceived coverage is a lot easier. LOL
 
But that is all you normally get!:D When you think your sprayout is covered, shine a light on the backside and it will prove you wrong 9 times out of ten.

Good point texasking. That's why the color of your sealer can alter the shade of the color you are spraying. Unless you get true coverage, but on a blue like that true coverage cold be 6 or more (probably more) coats.

That was all I was trying to get across, it sounded like he has been told to just spray a bunch of the hood past the stripe layout and then mask the stripes. I think the blue would look much different where he was spraying over the white than over the dark.
 
There are alot of pieces of this car to mask off,nosecone cowl,hood,outer tail panel inner tail panel valance decklid etc. Not trying to beat a dead horse here but what about this scenario... shoot the white past the tape off lines,then my intercoat,then tape off stripes,seal with proper sealer color and base car.
 
I did something similar today on a 2 tone silver bottom/dark blue top Chevrolet truck. The truck was sealed with black epoxy. I sprayed the silver bottom first, taped it up and sprayed the blue. This blue covers very well, but I still put 4 coats to (hopefully) cover. I considered spraying sealer over the silver overspray, but I have had the base have a reaction before, and couldn't make myself do it. Still think your best solution is to paint it blue complete and clear it. Then sand it with 400-600, spray your stripes, and reclear. If you get any overspray it will be easy to remove from the clear. I just don't want you to do all that work, then have the base wrinkle causing a big mess. If you do try it, wait at least 24 hrs. and spray a small spot with the sealer and let it sit a few minutes to check for a reaction. And make sure you put hardener in the base. Let us know how it turns out, because I would like to know if I'm just being paranoid:). Are you using epoxy sealer and how much are you reducing it?
