|A couple of months ago, I did a test
with 6 brands of paint to determine resistance to fuel. Here
is how the test was done, and the results.
Color Place (Walmart)
The test piece was a 4" x 12" piece
of lite ply. It was first coated with epoxy, then cured and sanded so
the paint would not soak in & affect the results. The piece was
masked and each brand of paint was sprayed in a 2" x 4" block.
The paint was applied in a mist coat, color coat, and then a final wet
The paints were allowed to cure for 10 days.
1. The paints were exposed to 15% nitro raw fuel and wiped clean.
2. They were exposed to 15% nitro exhaust from a Y.S .61 and wiped
3. They were exposed to 20% nitro raw fuel and wiped clean.
4. They were exposed to 20% nitro fuel exhaust from a Y.S. .61 and wiped
The results almost fixed after the first test. The first 4 paints
Lustrekote, 21st Century, Perfect Paint and Rustoleum were fuel
resistant to 15%.
The Krylon and Color Place paints wiped off on the rag when initially
exposed to fuel.
Further testing showed the first 4 paints would be fuel resistant in all
other instances, but the Krylon and Color Place got progressively worse.
Now here are a couple of grains of salt to use ....
The tests were done and the fuel was wiped off the test piece "almost
immediately". I can't say what would happen if it were to cure for
several days before being wiped, but it does appear, with reasonable care, the
first four paints will resist glow fuel up to 20% without adverse affects.
Personally, I would not use Krylon or Color Place paint on the exterior
where it will be exposed to glow fuel. Note that I said these paints
were fuel resistant. Paint gloss was not adversely affected and paint
did not come off on the rag when it was wiped.
These are just my results and by no means scientific. If you choose to
use them, try a test piece of your own first with the fuel you plan to
use. After all, it's your model and time, but this is the best I
could do. I hope it helps someone.
