Here's a thought...

I have redone many pieces of furniture, finished them off with a couple of coats of polyurethane. Excellent results. Now...can I use the same as the top clear coat on the '68? Factors like temperature, vibration and stiffness come to mind. They market a marine spar urethane that resists abuse. It's much cheaper, and I'm not looking at pristine showroom floor quality, just a nice stable protection coat.

Can I fill my gun and use it?

Thanks

The clear coat on a base coat/clear coat IS poly. However there are a couple of factors here:

1. What kind of paint is on your car? Poly can lift some types of paint.

2. If you have any experience with poly you will know it is hard to get a good looking finish. It cannot be put on with light coats, but needs thick wet coats to look good. And if the pressure is wrong it will orange peel (look at any factory job and you will see nothing but orange peel), too thick and it will sag or run. At least you can sand and polish the poly smooth afterwards given several weeks of drying first. But polishing poly is also an art to avoid burns.

Personally I would call the nearest auto paint dealer and ask them. They will know what is compatible and what is not. In any case I would only use automotive poly clear coat.

I have a '71 Z-28 that was painted PPG black, and the people used a hardener in the paint. My local paint shop told me that without the extra hardener the poly would lift the black paint. As it is I will be able to paint the white stripes (missing) with a white basecoat then clear coat the entire car.

Oh, and you will need to scuff the entire car with gray scotchbrite prior to applying the poly.

Listen, if you want to save a few bucks get one of the "value lines" like ONMI, NASON, Cross/FIRE, Dimension, etc. The URETHANE clears (designed for automotive use) are only about $50.00 a gallon. Don't try to save going that far out of the box.

Thanks for the replies....

I really don't know where to get the clear automotive urethanes...any recommendation, perhaps a website or two?

It could be an interesting experiment tho to use the marine spar.

Look in your yellow pages under paint dealers. Most dealers will be for homes, but there should be at least one that handles automotive paints.

Look under "AUTO paint and supplies" in the Yellow pages. Or simply stop by a local body shop and ask where he buys his paint. If you are going to be doing any body work or paint at all you really need to get to know the guys at the store that supplies the body shops.
