Hi ,
I noticed ona few posted pics , that some of you you use(d) a type of grey primer .
What kind of product should I use for an easy to apply primer ?
I'm looking for something to use over nitrate and butyrate dopes .
Thanks .

Probably what you saw was Duplicolor auto lacquer primer. I can now say I've used it. Seems to work OK over butyrate.

Randy, Does this come in a spray can ready to shoot?
-
yes. I bought it from the local Schuck's Auto parts in rattle can. Sands pretty well and I haven't seen any adverse effects thusfar. Randy Ryan seems to like it. That was good enough for me.
I should say that the stuff I actually shot came in a quart can and I shot it with a primer gun I have. But the same stuff comes premixed in a rattle can. Can't see that there would be any difference. It was the Filler/Primer as opposed to the Primer/Sealer. this stuff builds pretty fast.

Thanks Randy, I appreciate that.
The Duplicolor comes in both a sandable primer and a filler/primer in red and gray. The only caution I would throw out would be not to lay it on the heavy, it will slow the drying time ALLOT. Put on correctly, it will dry very quickly (allowing for humidity) and sand very easily.

>>(allowing for humidity)<<
Even when it's pretty humid, it dries eventually. It was about 85% when I shot it. But 24 hours and it was ready to sand.

A word of CAUTION here...
I cheeped out an went for the generic rattle can primer labeled "Brite Touch". (Yea, it was half the price of the famed Dupli-Color). Guess what? It went over my Nitrate base well. Sanded off "most" per usual. Then, since I was going for a yellow finish, I sprayed a light blocking coat of Randolph white. Well, it melted the primer which also shrank, leaving those little cracks all over the stabilizer finish. Several sandings, and careful recoatings with the Randolph covered the problem. :-[

All I use now is Duplicolor Filler/Primer (light gray) in a big spray can. It's just too darn easy.
I still have most of a gallon of PPG surfacer primer and a couple quarts of Dupont 131 Fill-n-Sand to use if I ever get crazy and want to go through the trouble of getting out the spray equipment. :##
