gloss over primer

[stevez]

OK, I'm doing an all white car, and wondering why not just use Tamiya white primer (fine), sand as needed, and then spray clear gloss over the primer.  The clear gloss will not attack the primer. 

  Interested in the pluses and minuses of this... before I actually do it...   Thanks.

No reason not to do it. Pluses include less total paint thickness and fewer opportunities to get trash in the finish material.

Steve Guthmiller used clear over white primer for the roof of this beautiful model, and you can't beat Steve's work. Good enough for Steve, good enough for me.

thanks, I'm doing the 65 Belvedere I, in all white, similar to the Bob Mosher cars  (MoparsbyMosher.com)

I've actually heard a lot of people do this...not necessarily with primer, but with flat paints, but the effect should be the same. Since cars built in the 50's-80's didn't typically have a "deep" gloss paint, you get a more period-correct look by glossing over a flat coat. I've got a few junker bodies that I plan to try it with, because flat colors lay down a lot smoother, and I tend to get heavier orange-peel with some cheaper rattle-can glosses (Krylon for instance).

Yes, you can shoot gloss over a (flat) primer and end up with a nice finish. I did that on a lime green '71 Camaro once.

With white, though, you always have to worry about your clearcoat yellowing with time. For white, I'd always rather go ahead and shoot a gloss white paint, preferably Model Master Classic White, which has given me good results.

I've not only had success spraying Duplicolor clearcoat over white primer, but I've also sprayed the clearcoat over gray primer with excellent results.  I'm not sure that lacquer clearcoats yellow over time...... I know that enamel clearcoats will.

I've got some good Cobra Colors clear gloss left over......should work well with primer white.  THANKS

I used Tamiya TS flat brown on the roof of my Moebius '53 Hudson.After I sanded out a few dust nibs I polished it  with Novus #2 and it came out beautiful.

Before I discovered MCW paints & the joys of lacquer paint in general, I used to paint all of my builds with Testors flat enamels & clear coats.

I liked the flat paints much better than gloss because they layed down much better, didn't have the tendency to hide detail & dried much faster than gloss enamel.

Back then I would shoot them with gloss enamel clear coat, although it was never a good idea on very light colors because of the yellowing problem.

This '53 was painted with custom mixed flat enamels & Testors clear enamel gloss coat.

I can't argue with any of that.

I shoot clear over white, grey, and black primers with no issues.  Sometimes I'll throw some Pearl Ex powder in the clear right on top of the primer.

I do this all the time. Almost all my gloss white, gray, or black cars are just primer, wetsand, and clear.

Whoa, I'll try the Pearl Ex powder method sometime. Thanks for the tip Jim.

I mix the Pearl Ex with some HOK SG100 in  a little cup.  Stir it really well and then into the airbrush.

Thanks. I'm definitely trying this on my next project.

And here it is. Model Master 34151 Interior Green playing the role of Citrus Green, which I didn't realize was metallic at the time.

I did a bit of spray testing on a junk body I have...I was testing Rustoleum Clear to see if it'd be viable to use since I can get a large can of it for like $3, but figured this would also be a good time to show a comparison of flat black vs. flat black with a gloss clear. That's the same flat black on the roof as on the front clip, with 3 coats of clear.
