Rattle Can Paint

LAST EDITED ON Dec-02-04 AT 03:02 PM (CST)
 
I have been using Rustoleum for some of my finishes with fairly good results after I thin the paint by heating the can. I also have read where others use various paints and clear coat of poly. Does the poly stand up well to fuel? Is the poly a durable clear coat? I was thinking in terms of using Krylon and clear coating with Minwax Poly??

Hey John,

I have used Krylon for the base coat and then covered with
spray polyurethane at least up to 10% nitro with no problems,
but the poly will yellow over time, if you have a repair and go through
the process of Krylon and poly the new repair spot will be lighter
in color but eventually discolor again over time. You already know
this but don't use water based Minwax poly because the fuel will
eventually eat through it. Some guys says it's fuel proof but over time it is not.

Select color schemes with cream, yellow, green, red, orange and you will never see the color cast of the top coat! I have a silver cowl ovecoated with Minwax spar urethane (the outdoor stuff for heavy UV exposure) and it has no visible color change even next to blue moneykoat.

One caveat, the urethane overcoat will NOT stick to Rust-Oleum metallic colors. Peels right off like you applied several coats of release agent. Guess how I know The finish makes a nice display model though.

Hi John,
Learned a trick last week about spray paint cans. Find one of those gallon can shakers you see at paint stores. Install the spray paint can. Shake well. You'll see how much longer the spray paint will go. That little ball in the bottom of the can just isn't up to the task of getting the paint stired properly. Take care, Erich

Works good. The Hurricane is camo Krylon. light blue Rustoleum, and Minwax satin clear coat to dull any shine and fuelproof the Krylon.
Only problem is that the silkspan is very brittle over the open bays with none of the give you expect from dope over silkspan.
BTW, the silkspan was attached and given 2 or 3 coats of nitrate dope but still brittle.
It's also a little heavyier than a dope finish.

Looks like there's a lot of interest in rattle can applications so here is the information I gathered from the sources. Krylon tech support says you can use any of their lacquer based cans ie; the ones with the five colored balls on the can, then for a protective coat they recommended their sister company "Dupli-color" product # DE1636 which is a clear engine enamel. Tech went on to instruct on proper application for the clear, which is proper cure of base coats and then make sure the humidity is below 45% with an air temp above 65 for best results. They were unable to endorse the minwax or stoly products as they have not tested them. They did however inform me that "Deft" sanding sealer would work well as a primer for their rattle cans. Hope this helps. If you have questions call them at 1-800-4krylon and get it from the horses mouth so to speak. Thats what I did.

Cover with plastic, tape, buff and paint with Rustoleum. My Brodak Buster is done like this and seems to be pretty durable.

Dang. Godzilla's Rattlecan Paint instructions seem to be gone from the archives. If I recall correctly, he said to give the plane multiple very light dust coats a few minutes apart, using acrylic lacquer (i.e. Krylon and the like). The final clear coat would be two part auto clear applied using a paint gun, but some rattlecan clears should work (I've tried it with Ace Polyurethane and it works fine..). Don't worry about the gloss, it comes with the final clear coar.
