Repainting?

Postby GT_Indy » Wed Aug 01, 2018 10:08 pm

Those who repainted their Beretta.
What all did you do to prep the car?
What chemicles did you use to clean and/or strip the existing paint/metal?

Should I strip the paint down to the metal and redo the primer? It flaked in a small spot on the roof and I touched it up temporary but I want it to have a strong foundation.
What primer do you recommend?

How did you remove the rear side window trim?
The other window trims and stuff I can take apart but Ive never figured out the side windows.

The GTZ paint is not perfect, the hood has yellowing blemishes and the other paint shows some aging and it bugs me. I want to redo the car in the factory white and add clear coat on top.

Drying time how many coats of each and how long should it dry?

I blocked the stock paint and used Scotchbrite on the spots that aren't flat. But I'd recommend going to bare metal with epoxy primer as the foundation. That's what I did with my next car.

Whatever you do, don't use cheap mail order paint. Mine looked great for a few years but didn't last. Had to redo it with good stuff. The paint manufacturer will have specs for flash times, coats, etc..

Side window trim on the early cards just pops off. Run a credit card behind the trim to find the plastic studs.

I didnt know there was an epoxy primer. Thats kinda cool.

I will try the credit card trick on the rear side windows. I hope the trim comes off easily.

Yah I want to get some quality paint on the car. I want it to look nice when I drive it.

Yep, epoxy primer, and use a good automotive paint (I like PPG) with a hardener and reducer. Harbor Freight has a decent little air sprayer (20 oz gravity-feed) for $10-$16, depending on coupon sale, I did the two-stage (base-coat/clear-coat) on my Z-24's fenders with it, and am now finishing up a '46 GMC for a friend with it. Keep it clean with acetone, it will last a lifetime.

Be sure to use a good degreaser/wax remover to wipe-down the whole car first, keep a bag-o-rags handy and make sure the compressor has a water/oil filter. Be prepared to wet-sand the whole thing down after each coat (primer and paint, probably clear-coat too) and finish it off with a good two or three-stage buffing compound (we tried Meguires, but it wasn't as effective as we hoped, so now we are using 3M and it is great, though twice the price) if you want it to look as good or better than factory finish. Otherwise, you will have orange-peel texture and possibly dust contamination causing less-than-perfect finish surfaces. For my Z's fenders, I built a filtered and fan-vented hot-box just the right size for the parts, but that is difficult to do for a whole car. My fenders still look good (slight orange-peel here and there but I didn't sand between coats either), with a few blemishes including a 1-inch diameter spot where the clear-coat popped on one, but those were done maybe eight years ago? No complaints here.

Thanks for the information, I didn't know I needed to do all of that as well. I will look into it.
That helps put a dent in my research. lol.
Yah I'm not sure about the degreaser/wax remover. I know I want something harsh (that takes paint off too) because I want to have a good foundation. I'm not sure the flaking paint is good to paint over.
I temporarily used touch up paint and clear coat on areas where the paint flaked, keeps metal from rusting, hoping it lasts till I get everything and go for a repaint.
This car is spotless, zero rust, mint interior, I want to bring the paint to the quality where it should be.

If the paint is flaking, you have no choice but to remove it all.

Yah I agree. I'll look into a paint stripper or something.

What about the primer? Should I go down to the metal or do you think the existing primer is still good enough?

The primer is the issue here, the paint has not stuck to it. Bring the car to bare metal and start from the ground up. The foundation is what makes the paint job, don't skip it and think what GM sprayed down is good enough after 27 or so years...

I agree, I want to do it right. I'm thinking the paint is original, but the hood looks like it was repainted to me.
Do you suggest anything specific that can melt the paint off the metal?
Should I buff or sand the metal?

I did my whole Camaro with 80 on the DA after trying to do the roof with stripper. F that noise. It's a nasty mess and doesn't work worth a damn. The DA takes quite a while but it does a good job on the flat areas.

Another option is to get it professionally blasted. I would have loved to use my dad's new rig back when I was working on mine.
