Does a glossy fuel proof top coat (applied over a krylon fast dry spraypaint on a plastic cowling)-exist? I've read a few threads about fuel proofing firewalls by thinning epoxy. Does this provide a decent finish? Thans for your input!
Derek

Do not use thinned epoxy over paint. That would make a real mess of things.

If you want to make absolutely sure the clearcoat is fuelproof and will not yellow when exposed to the UV rays of the sun, automotive clearcoats are the only way to go. I have never found any other fuelproof clearcoat that does not yellow and darken the paint.

I second that. All hobby clears that I have tried are yellow. Krylon is not fuel proof. Automotive 2-part clear is crystal clear and fuel proof. It is fairly expensive, but if you keep it climate controlled, it will keep a long time.

Sounds good, I guess I'll have to make a trip to the auto paint store. Thanks for the help guys!

PS. Be sure to test it on a scrap before committing it to your plane. Also test it over surplus decals if you plan to use them.

Auto Zone sells this enamel clear-cote spray that works
good....

flyboy dave , Is the clear fuelproof? Vic

Yep, and it's only like $3.79/can.....
sprays real nice, no splattering....drys fast and hard.

....looks ok to me....

What kinda of paint is that that you sprayed the clear over?

Krylon will crack or spider web after awhile under Lustercoat clear. BTDT.

The same stuff....Auto Zone ''engine enamel''....
It is extra resistant to gas and oil....same low price.

I sprayed 4 mist coats of color, and came right in with the
clear....3 coats....10 mins apart....(no runs)

It only comes in basic colors, though.....

Flyboy Dave,

You mentioned, "It is extra resistant to gas and oil..."

How about glow fuel? Can you use it as a clear coat for a model with a glow engine?

Any experience with using it over Rustoleum?

Thanks,

(Deleted) - somehow posted same reply twice....

Flyboy Dave...Does the AutoZone clear stay crystal clear over white, or does it cause the white to appear yellowed like other one part clear coats?

Thanks,
Jim

Jim....I can't tell you....others have asked....I painted
the clear over YELLOW !!! :stupid:

I painted
the clear over YELLOW !!!

Isn't that cheating?

Ya Know, kinda like putting a K&B 61 together from inexpensive used parts. (oops wrong forum)

....your right, I'm terrible.....I'll change my answer....

Zabel....So far....the top-coat appears to be crystal
clear....with no signs of yellowing what so ever.

( Ed....if the plane turns orange, I'm in deep doo doo )

LMAO.

I'll keep my fingers crossed it doesn't, cause that's one of the finest can jobs I've seen. :thumbup:

....don't tell anyone about the Polka dots....
(...er...make that "digital" dots...)

Dave.

The gloss looks good, but that's the weirdest looking tailweight I've ever seen!

....no, you can't have a sip....and don't mess with my
"lucky flyin' hat"....

( Aren't you supposed to be working ? )

Flyboy Dave:

What is the part number of that Dupli-Color clear enamel spray can?
Thanks

Bob J.

....# DE1636....

Dave.

does it come in a flat finish?

Not that I know of....
