One of my buddies, Jerry Day, used Krylon Orange on his TF Tutor. With some care, it worked ok, but when he broke it, and needed to patch the silkspan, the troubles started. Clear dope to apply a patch to the wing caused wrinkling of the Krylon. He ended up spraying some Krylon into a jar, and using that to apply the patch dry, which worked fine. After drying, then water shrink. I don't know what the next step was, but possibly he used clear Krylon to start, or clear dope. Personally, I'd avoid Krylon.
Another buddy, Mike Haverly, has been using various dopes (Certified, Randolph, SIG, and Brodak) with Dupli-Color color spraycans from the auto parts stores. Under or over, no problems. Lots of colors available in Dupli-Color, too. Most recently, he's started using 2 part automotive clearcoat for the topcoat. H^^ Steve
Bill, is that automotive Duplicolor fuelproof by itself?
If you'd stay out of the prop that wouldn't happen so often...
As to the Duplicolor Automotive Lacquer: My son, Aaron's, last trwo planes have been totally color painted with Duplicolor over whatever substrate we used at the time. Mostly Sig Nitrate, Duplicolor filler/primer and then the Duplicolor colors. Topped off with NAPA Econo 2 part clear. One is a Satana the other is an Oriental. No problems after a year or more!
I also used the Duplicolor "Metal Cast" paints (lacquers) to do a Candy Apple Red finish on my Tomahawk. Aaron did a power on inverted landing (not his fault!) which tore a little covering and knocked off the fin/rudder. Used Sig Lite coat to apply the patches, reprimed, and finished like original, no problems.
YMMV!
Funny you mention Duplicolour paint Big Bear. Tonight I was standing in an Autozone store, wondering if the Duplicolor Grey primer/filler was a lacquer based primer suitable for stunt use. Was looking for the Sherwin Williams primer but neither Advance nor Autozone carry it around these parts. I guess looking at Napa is next on the list.
