Rated 5 out of 5 by from High Build Polyester Primer Polyester primer is the king. Easy to sand. You can get after it pretty hard without burn through. The best part is it does no shrink and crack like traditional high build primer. This is all I use now.

Rated 5 out of 5 by from Good stuff. Amatuer here. I have tried a few different types of high build primer. This stuff is as good or better than the high priced brands. It is now my go to HB Primer.

Questions & Answers

This only comes in light gray, I want a dark base for my base color coat. What's the easiest way to go over this to give me a dark gray base? Would dark gray lacquer primer be acceptable as just I happen to have a gallon sitting around?

Can this be sprayed on top of rattle can primer?

Asked by: Aaron
We can not guarantee compatibility with anything we do not sell. You would have to test a small area first.

I mixed up 16 oz., used a drill to mix well, new gun with 2.0 tip. Material sprayed fine but went on thick & speckled with tiny gobs (like sand) all over the panel, why? It sanded out fine. Can this be reduced to spray lighter as a final primer coat?

Asked by: rick
This product is not recommended to be reduced. However, this product will have a slight texture to it due to the high build finish of these primers.

What is the best method to measure out the catalyst in 1/2 or 1 ounce portions?

Asked by: Emargerum
I looked up on the internet figures as to how many drops are in an ounce, etc. As it works out, about 9 drops of catalyst to the ounce of material (closer to 9.25 actually, just get as close as you can). I've been using this method for mixing up 4, 5, 10 ounce portions etc, at a time and it's been working great.

The description says this can be used on bare aluminum! Yet at least 2 people have specifically asked about that here, both answers were to always use epoxy primer on aluminum first. So, which is it, can you or can't you? Maybe some factual consistency?

Asked by: rick
USC High Build Primer/Surfacer(50776ZP) is a high quality Direct to Metal(DTM) Primer Surfacer that has excellent adhesion properties and will work very well on bare Aluminum when the surface is prepared and cleaned properly. Go to www.eastwood.com and type in 50776ZP on the search bar. There you will see the product and its description.

Can i use under an acrylic urethane sealer and paint and do I need to thin it with something ?

Asked by: GPCAT64
Our paint is acrylic urethane based and is perfectly fine underneath. We can not guarantee compatibility between this and brands we do not offer in general though.

So technically, I can grind a panel to bare metal, bondo imperfections, 120# the whole panel (or vehicle), apply this, dry sand with 400# and go right to base/clear? ("Technically"! Not saying I wouldn't use a sealer.)

Asked by: rick
Technically Yes!! This is a Direct to metal(DTM) product so it can be applied to bare metal and will fill 36 grit grinder marks in 2-3 coats. Then 400# sand and paint.
