I have a '67 coupe and was going to be painted by a friend. He had me do the sanding on it to get all the old paint off but down to the original paint/primer. He painted the fenders and a portion curled on him. He said he did not no why and I started to investigate after bringing the car home before we went to far and put all the prep/sanding work in and it turned out like s***.

Now after talking with some people it turns out that the paint he was using is a laquer based paint and someone said this is not the kind to use because of yellowing and cracking sometime later. I should be using urethane based paint.

I understand the concept of it curling just as if you use water-based paint over enamel in your home.

Now that the engine compartment, trunk and front inside wells are done and assembled, do I have to take the whole thing apart again to spray it right or will the lacquer based paint be ok and last a number of years even in the sun?

 

Where the hell did your friend get Lacquer paint?

I haven't seen it in YEARS.

IDK, if the fenders get fixed, and the rest of the car looks ok, I don't see any penalty in running the paint for a while. Lacquer can be buffed out over and over (up to it's thickness) and brought back to life several times, eventually it will "check" but if I were you I would think about crossing this bridge when I need to cross it.

 

autozone sells lacquer in the Duplicolor cans.....

you need to strip off all the lacquer....i would take it down to bare metal and start fresh

i would sand to bare metal and coat with an epoxy primer then wipe your filler re epoxy prime your body work then use 2k primer....

 

This is a PPG lacquer based paint, bought approx. 3 months ago. How long before it will "check"? Is there a different route I should be considering such as urethane based or enamel based paint? The VOC laws are changing in CA at the end of year and do not want to use the waterbased paint!!

 

buy paint across the state lines....wait wut

seriously do it right and do it once...use a nice bc/cc system

the lacquer will last a little while but if its lifting and wrinkling up on you it might do the same thing when you go to prime it to fix this problem...although you can spray the primer very light after sanding the junk paint off almost dry spray it but not quite dry and it might not lift on you again
