wrinkling or cracking paint
corrado vr6 - 29/8/10 at 09:56 PM

Evening everyone,
Some of you may remember that im spraying a my van, yes thats right im still doing it, its taking some time only being able to do it in my spare time!! Over the weekend i managed to spray the metallic silver on and i must say im really impressed with the results thanks to the advice i was given from my last few posts.

However one thig that has realley pee'd me off is in a couple of places it started to wrinkle or cracking on in about 3 areas all where i has used etch primer i only found this out this evening from doing the only thing i could think of and that was to rub it back revealing the layres of primer then etch primer it seems there has been a reaction but only in some areas not all the etched areas. at first i thought it was bad prep ie not degreasing properly but still not sure.

So far i have rubbed back the areas with 500 grit wet back to bare metal so now im thinking etch prime again then primer then spray the whole panel with the metallic paint, however im worried about the scratches from sanding showing through so not sure what to do obviously the primer will fill the scratches i have just made but when i need to rub the primer down im going to need to blend it into the silver already on the rest of the panel scratching the silver again should i finish on the 500 grit which is what i finished on before i sprayed the silver anyway,i feel i should go higher in the grits to stop the scratches showing through but dont want it to look different to the other panels.

Any help will be much appriciated, as im really gutted that this has happend was hoping i could finish it this weekend so i could crack on with my kit but it just seems one thing after another lately!!
Thanks Greg

I always use 1200 grit to finish, prior to putting top coat on, but, I am only a DIY sprayer so may not be correct. HTH Ray

Im not sure what you mean but if im right with base coat being the colour then yes i have just sprayed the colour (being silver mettalic) it wrinkled or cracked so i have rubbed back to bare metal in those areas, but im now unsure what to do. Sorry if first post is confusing i know what i mean as im typing it but reading it back
doesnt always make sense!

Edited to say it's 2k if that makes any difference
