What all do I need to know about epoxy primers? - The 1947 - Present Chevrolet & GMC Truck Message Board Network

**68 Stepside** · 05-06-2002, 06:44 PM

I've been wondering, I know epoxy will hold up a lot better. Is there any special prep-work involved in spraying epoxy primer onto the clip of my 67? What are the fair prices? How much would I need to do the complete front clip and doors? This place doesn't seem too bad on pricing, but I don't know: http://www.southernpolyurethanes.com/epoxy_primer.htm

Are there any other epoxy paint vendors that I should know about?

Any ideas/comments are appreciated.

Thanks

TJ

I apparently need an activator to go along with it.....do those prices seem to be fair? I think the panel would look good in white.

If memory serves, the epoxy primer is water proof and will not caus rust like normal enamel primer will. It is also called sealer. Real good stuff, but does not have the build up quality of the enamel.

For epoxy primer, that's a nice cheap price. PPG makes DP40LF (lead free) which is gray-green, they also make a couple of other colors in the DP series. It also requires activator. Theirs is about $100/gallon for the epoxy alone.

It is true that epoxies adhere very well to bare metal, it is true that they are moisture resistant, and it is also true that they don't have very good filling qualities. But, you can use epoxy on bare metal then use urethane or even lacquer primer for fill. For nice jobs, use urethane which is more stable. Lacquers sponge out and swell every time you apply a fresh coat.

I'm going to bookmark that site where you found the epoxy primer; I have to do a '68 Chevelle vert and a '57 Belair one of these days, and I'll need many gallons of epoxy.

Thanks!

One more thing about epoxy primer..... you need to topcoat with primer or paint in a certain amount of time or it will require scuffing with a ScotchBrite pad. If it is allowed to dry too long, it will become so hard that the topcoat won't adhere to it properly. The paint manufacturer should have a spec sheet available that will tell you all the necessary info like mixing ratios, induction time (if any), pot life, drying time, etc. DuPont's webiste has all the info you need on their products.

I'm sorry, I forgot to mention that it'll be the top coat....

Are there any other special prep things that I need to do? And I take it I need to buy that primer above, with the curing agent as well, right?

Thanks

All paint manufacturers have good tech sheets on each of their products, that you can get from the paint store, just ask. They give good tips on prep work, mixing, shooting & compatability problems. Always study these sheets before you start shooting. What's that old saying, "If all else fails---read the directions"? That really applies to paint!
