An alternative to dope?

The problem I've found with Rustoleum, is that you "used to know" what type of paint it was.. and I always looked for "Alkyd-enamel" on the label when I bought any. I can't find that anywhere on their labels now.. so I don't know if that's the actual paint-type. Alkyd-enamel is fuel-proof.. but some of the other paints obviously aren't. If I can find Epoxy-paint in the color I want.. I'll usually get that type. These two paint-types are HEAVY when compared to a lacquer finish.. but they can cover in 1-2 coats. They do however take a LONG time to dry.

I've heard of Krylon being used. Similar procedures, similar 2 week cure off, similar performance to fuel resistance. Rustoleum is easier for me to get.

I would test some first. Take the colors you want, apply to a 2x4, wait 2 weeks. Wet a paper towel with fuel. Apply to the paint, cover with plastic, come back 30 minutes later and check. Slight color transfer with light rubbing is fine, wrinkles and washing away are not.

I bet a large number of "generic" "enamel" paints will pass.

Yes, I was thinking of a test piece first. I have so many 1/2 full cans of spray paint in various colors including engine enamals which might work even better.

Perhaps a coat of sanding sealer or any standard wood sealer followed by light coats of color. Experiments to follow.

I've used a few different rattle-can finishes. Remember Pactra's "Formula-U"? I still have a few old cans of it. I used "International Orange" on my Barbie Plane almost 25 years ago.. and flew it a lot! The gloss has held up well.



I've always been in the habit of "spritzing" my glow-powered models with cleaner.. immediately after the final flight. I'll throw a rag over the engine.. and spray the model with w/s washer-fluid that I keep in a small pump-sprayer in my flight box. The alcohol cuts the oil.. and I think the evaporation process might carry the nitro with it.. not sure, but it does a good cheap job of cleaning IMO. The longer you leave that fuel-spray on there.. the more you're testing the limitations of your finish.

The Dope is not too bad if your outside and having beer with it //// I got some of the \Rustoleum paint at the Wal-Mart 3.77 a can to try myself mainly being the price and easy spray app. Question , I got this stuff for the cover fuel proofing ...   anyone tried this stuff ?

I have not. But I was in Wal Mart's auto finish and trim section looking at sandpaper and other repair products, and saw a can of Rustoleum clear, among a couple of other colors, labeled "Lacquer." I should have taken a picture and looked it up.

Not sure how helpful this was.. but there's helpful hints on application. I would read-up on the method of "clean-up" which if different between the two; may give a clue as to which one might be better for a modeling application.
