If I'm wrong, please let me know, but I think:
After degreasing/scouring/cleaning, Rustoleum Silver spray can enamel will bond w/o primer to iron-on covering, but isn't fuel proof.
Min-Wax water based Clear Gloss Urethane is compatible over enamel and is fuel proof.
Anyone have experience with this?
Thanks.

I think that might work but the Rustolem is a heavy paint and my experience with Minwax (polyurethane)over open bays is that in about 6 months it will begin to develop spiderweb cracks and look like crap. What about just removing the existing iron on covering and redoing it in silver?
-
The plane was acquired used and finished.
I've no experience with iron-on other than poor attempts to patch it, and I'm for E-Z on this redo.
The covering is in good condition and silver is pretty light if applied only to a "reasonable enough" look, w/o heavy coats.
Have you a recommendation for a suitable clear coat for fuel proofing?
Thanks.

Another idea then...
I think some guys use the automotive "Dupli-Color" rattle can paint, which to my understanding is fuel proof. It's available in a lot of different colors. You might give that a try and then you wouldn't have to bother with clear (and it's extra weight).
-
Thanks Wayne - sounds even better.
I've seen comments on Dupli-Color but nothing about their metallics.
I should be able to find it locally and give it a trial run on scrap first.

And, as with any paint, give it a good long chance to properly cure before you head for the flying field.

Water-based Minwax (and other) polyurethane isn't fuel resistant. The regular Minwax polyurethane is fuel proof. Two different products, one is, one isn't. H^^ Steve

Noted and filed Steve - tnx for the correction.

I don't think any of the Dupli-color clears are fuel proof. I use a lot of Dupli-color products, but only the lacquer for color. The lacquer has to be clear coated and I use auto catalyzed clear. My understanding is that the enamel colors may be fuel resistant, but the clear enamel is not.
Regarding Minwax, the water based product is called Polycrylic, the solvent based is Polyurethane. Polycrylic is not fuel resistant. Polyurethane is heavy and will yellow a little over time.
I suggest using the clear catalyzed spray can product Charles has found and reviewed in a recent thread. I am considering this for my next project. Hoping to get away from the auto paint. Difficult to use and very expensive. KBS receives good reviews, but I have never tried it.

Yes Paul, Charles recommends Spray Max 2K, though cautioning that a respirator is a must when applying it.
Even so, I've about decided that it's the most suitable for my project.
The KBS has generated a following and I guess is arguably the best product on the market.
It's a bit of a hit in initial price though.

Terry,
I believe it was Dennis Toth who introduced the 2K Spray Max to me, probably a year or so ago? He mentioned it in one of my Threads.
I didn't even know they had 2K clear in spray cans.
I'll be picking up a few cans of high gloss clear for the ARGO.

I have a can of 2K on order but, as you know Charles, since the wing is white iron-on, I've decided to go with a different color scheme that won't require trying to "aluminize" the whole airframe.
More later w/pix, as things progress. S?P

An FYI on the 2K spray @ $21 - I got it today, a 2-part-in-1-can product w/a push pin underneath to activate, and see on the can that "pot life" is only 48 hrs, so pretty wasteful unless you schedule a lot of clearcoat at one time.
