Painting a C3 Question
Those of you who have painted a C3:
- Do you recommend leaving the headlight covers (lids) in or out to when painting?
Mine are out at the moment and it seems like it might be easier to paint them separately, then assemble.
One reason, is because primer and paint will get into the gap around the lids and into the front area, which is currently black. Is it common to tape off the gap around the headlight lids or not?
- Do you primer the door hinges? It looks like there was no primer on the door hinges, originally. Is it common to just spray on color? (I'm using a 1K paint.)

Couple of thoughts for you;
I would check out the SPI paint forum and ask there. Quite a few knowledgeable and professional painters hang out there and are happy to help.
www.spiuserforum.com/index.php
And, I think it depends on what you are painting. If a metallic, you want the paint to all match, so I say install the lids. If a solid color, maybe not an issue. And I would tape the backside of the lids, doors, ect to manage the over spray.

I suppose I could paint the inside edge, then install the lids before final coats.

I just test-fit the lid and headlight frames into the front-end and there was no issue. They may be installed either from the top or the grill openings, as long as you have everything out of the way. The car currently has all vacuum system components and grill off.
The paint I'm using is a single-stage, so spray direction shouldn't be an issue.
Anyone have an opinion about priming the door hinges? Seems that GM didn't always primer all parts (even metal) when they built these, but I'm all for doing the job right (even if it's a little different than factory). I don't want issues down the road.

Paint the undersides/edges with them off the car.
Re-install exactly as they should be.
adjust the stopper so the lid is below the body. this will allow to get get pretty good coverage around the gaps.
On the final coats. Adjust the stoppers so it stays open like an 1/8 of an inch above so you get the lid edges as well.
You will get some dryspray/overspray on the underside/back edges of the headlight,
you can lightly buff that area but its hardly noticeable with the lights popped up.(at least it will be colormatched.)
Also, is it 1K Single stage with hardener or just reducer.
Check the techsheet. I would use recommended hardener/activator, it will help with durability, and repair/recoat/fry-ups/chemical spills etc.
and yes, use recommended primers on surfaces. it will help with adhesion. some of the metal pieces use an etch primer or some coating for the factory paint.

The paint is Sherman Williams ZTX HP 1K. It uses a 4:3:1 ratio of Color:Reducer:Hardener
