Sprayed some epoxy today.

Good let them avoid it. It has always worked for me. Like putting plastic right over metal with out epoxy under it.

And I am not recommending any one does it but it has worked for me for a long time.

Using lacquer primer on bare metal is not comparable to using filler on bare metal. Modern fillers will adhere quite nicely to bare metal, and I do not have a quarrel with that technique at all, except to note that corrosion protection is enhanced when epoxy is used to seal the metal beforehand.

I repeat, using filler on metal is still acceptable (though not best).

But modern lacquer primers are bottom of the barrel. While they may work acceptably well as surfacers, they will not give anything close to the adhesion or corrosion protection of an epoxy when used on bare metal. Modern lacquer primers are not suitable for large bare metal areas, especially when the metal has not been treated with appropriate acid cleaners and water rinsed, which cannot happen in the presence of body filler.

So to continue to use an outdated technique when the proper materials are right in your hands, is stubborn at the very least. I would bet if you got over the resistance to change and just tried putting epoxy first on top of your bodywork and bare metal (note that I am not even insisting on putting it under filler here) and then use your lacquer primer on top of that, you would achieve a result that would be no harder to work but would be vastly better for the vehicle.
 
When someone says that they have been doing it a certain way for 37 years, I quit listening. Hopefully anyone new to this would too. Things have changed a little in the last 37 years. Telephones were attached to the wall and many didn't even have buttons to push, they were rotary. Many people still had to get up to turn on or change the channel on their TV. Gas was about $1.00 a gallon, kids had to learn how to tell time without a digital clock, and add without a calculator.

Anyone that thinks that the lacquer primer of today is anything similar to what we used that long ago, needs to quit working on cars. They know not what they are doing! Plain and simple.

I never said I used laquar primer over metal. You just assumed that. First off I usually work on Corvettes so corrosion protection is a non issue. The car I am doing now I took it down to bare metal then did my body work and then shot the whole car with Featherfill, after I sanded that I went over it with the durabuild to fill the sand scratches. And to block sand it. I am not going to use expensive primer to just sand it onto the floor. After that I seal it.

And I can't see how this has turned into a big discussion here. This is how I do it and it has always worked for me.

I just posted this thread because I never used SPI products and hoped to get an idea on best mixing and spraying pressure. I didn't post here to get a big lecture from someone telling me that what I have done for long time is not right.

And you shouldn't call people stubborn. I take that as an insult.

I just love know it alls. Because that is the way you are coming off. I am selling all my cars and tools starting today because Aaron said I should stop working on cars.
 
Everyone here that knows me knows that I tell it like I see it. If that bothers you, OH WELL. I don't claim to know it all, just more than a lot of people. Selling your tools is up to you, but if you are going to continue using lacquer thinking it is the same as days of old, then it is probably the smartest thing you have come up with.

I really don't see what the problem is. It is my car, my time and my money. I use it to fill scratches and block sand my car. I have never had any problems with it. Bottom line is it does exactly what I need it to do. End of discussion.
 
Why not just use the 1 part spot putty to fill the scratches. It's the same thing and will do exactly the same thing, shrink up later. The problem is that you are posting that as if it is thr right way to do the job. In fact it isn't and shows a lack of knowledge of the right way. New people come here regularly to get the right information, and in fact many of us came from another forum because of the problems with the wrong information being posted all the time there. If you want to do shoddy work, that is your choice. Just don't post it here like it is proper, because it isn't .

Everyone is invited to come here and learn, share good information, and socialize. If you just want to pass on bad information, Hotrodders.com loves to add their membership and has plenty of people that simply want to do it cheap, not right.

Aaron you are really becoming annoying now. I never said the way I do things is the right way, I only said it works for me and I never had any problems. Like I said before end of discussion.


And something isn't wrong because you say it is. People are all individuals and do things the way they want. It's called freedom and we are protected under the first amendment to do things as we see fit as long as it dosen't hurt anyone else.
 
"Aaron you are really becoming annoying now."

Even that is wrong. I have been annoying for quite a while now. The great thing is that I am still right and you are still wrong. It has nothing to do with the First Amendment. No Amendment makes you right when you are doing something wrong. It simply gives you the right to do it wrong as long as it doesn't hurt someone else.

Aaron
 
The only thing that is wrong here is that this thread wasn't closed before you became a jerk. And I am putting it mildly.
 
That couldn't happen as I have been that way for years. I'd bet you've been ignorant for a while also.

If you're acurate, you don't have to be polite.

Okay.. This thread has went to shit and no need to continue..

Ive been out of town for a week or I would have already stopped it..

Facts are facts.. Mr Goat.. I dont have a problem with you doing things as you see fit for your personal projects.. Nor do I care what you do for customers.. I will not even engage in the debate over the lacquer being used to fill scratches.. There is no debate.. as I said earlier facts are facts..

I ask of 1 thing from you sir.. Dont suggest that to our members here is all.. If you do so, I can assure you it will be quickly blunted and I will stand behind it..

I will also speak for spi and say if you are going to mix lacquer in your jobs, perhaps you should find another paint line to use.. I ask you not take my statements as being an ass since I have no malice in my posting here..

This thread is over.. Lets leave it as such..

Happy Spraying
 
This thread has been a real adventure here. From seeking a little advice on how to properly spray SPI epoxy. To you telling me not to use SPI products if I don't use them as YOU see fit. I guarantee there are alot more hobbyist on here that are using lacquer like I have that won't admit it. I still don't see any problem with it because I have never had a problem with it. I have been to other forums that guys use it all the time to do exactly what I have and nobody seems to have a problem with it's use. Maybe the pros on here are really that much more knowledgeable than the rest of us.
