I use Chromatic 1010 water borne acrylic for everyday work.
Thumbs down on the PB oil base high build.
I like PPG's high build primer the best. Awesome, smooth sanding, flashes off in minutes. But you have to spray it, so it's not very practical for small stuff.

We have also quit priming. HDU accepts any type of paint; the only factor being how smooth a finish is required. Depending on the job we use acrylic latex or 1-shot, and build up the background with several coats. Currently we have a carved 15lb. HDU job in the shop being painted with black 1-shot. Four coats have produced a reasonably smooth and acceptable finish. If the job requires a background color more likely to fade, such as dark blue, we use acrylic latex from Benjamin Moore. My only complaint with acrylics is the need to use a lot more paint to cover and fill completely.

I was discussing this at Mass Mayhem with Mike Zee, he is also dumping a whole lot of 1 shot on unprimed hdu, doing a demo piece he says " Hey check it out, thats only 5 coats".... Five coats? I said thats a lot of paint and a lot of time & personally I was not impressed with the finish. I would save time and money by using Jay Cooke primer on the first 2 coats, and 2 coats of finish (Ronan Bulliten) Also, another theroy I been playing with: 1 coat of fiberglas resin 1 coat of automotive primer 2 coats of automotive single stage urathane finish
this gives you a smooth as glass finish and hard as a rock with a long life expectance

Capt.,, How do you sand that Jay Cooke primer. It is the worst sanding primer I have ever used. It also released and peeled up from the (cleaned) HDU and cost me approx. 2 days of redo. I use the Coastal FSC88WB (waterbase) primers with very little problem though.

Jack, I had the same problem with "balling up" on the sandpaper and the peelup on a $5k sign! I also went to the FSC88WB. Also, taking advice from some here on the BB, I started rinsing off my HDU under a strong stream of water in addition to my blowing it off with an air hose. It gets dust that the air fails to.

I never clean it just cut it, brush it off with a 9" brush and prime it twice, then I put one coat of finish on sand and one more coat, if I want a smooth glass finish I use the automotive urathanes hmmm.... if the stuff is urathane foam, what better to stick to it but urathane paint!

Well you guys helped alot. Five coats does seem to be alot. As far as glass finishes, a good coating of One-Shot over a good priming is plenty glossy for me. I Appreciate your replies as always you guys/gals never let me down Thanks!!
