Hot Rods Quick question for the paint pros...

So... I’m wanting to repaint the glass fenders on the red 32 car to get rid of some minor defects. They’re already painted in single stage enamel and I’ll be using the exact same paint again.

Do I need to prime them again or can I get away with just cleaning them real good and scuffing them down and blowing a couple coats of color over the existing finish?

Got a couple minor rock chips that will sand out on the left fender and the right fender has a spot on it that when it’s in the full sun you can see the primer showing through a bit. No one else notices it but of course since I know it’s there I can’t quit looking at it. Just want to do a quick clean up on them.

Thoughts?

Thanks in advance.

That should work just fine.

 

Do it...you will be fine.

 

Before you do any sanding , wash the panels with a wax remover , you can drive contaminants into the surface with sanding a waxed panel , many of the was products contain silicone and other stuff paint won't stick to .

 

^^^ This is an excellent reminder. When I get them pulled off I’m going to wash them real good with full strength simple green and then wipe them down with degreaser or lacquer thinner before I start sanding.

Hopefully that should be enough.

Thanks for the help.

 

Use caution, lacquer thinner has been known to lift some enamels, stick with wax & greaser remover only.

 

X2 on the Lacquer thinner, Noooooooooooooo don't use it. Wash real good with Dawn dishwashing soap first, the sand and wipe with degreaser and tack and paint.

 

I’ll pass on the lacquer thinner then. I’ve used it before but only after letting most of it evaporate off and using the rag as a kind of tack cloth.

Probably best not to risk it and stick with the wax and grease remover only though.

 

The only primer you might need is to spot in the rock chips, when you sand them out. Probably hit bare 'glass when you get them done/

 

Excellent thread.
