> Prime & Paint
With priming and painting of the E-flite Texan in full swing, I'm running some additional tests for fuel proofing paint. My initial findings are:
Good: Testors Model Master enamel paints work great when applied on a primed surface (Rustoleum spray primer) and sealed with Krylon Polyurethane. I performed a fuel test with engine muffler oil and also with straight 15% nitro glow fuel and neither budged the paint after 5 mins. of sitting on the test strip.
Bad: Testors Model Master Custom Lacquer System has to be done in the 2 step process Testors recommends. When laying down Hugger Orange (990) and then sealing with Kylon Polyurethane (plus 1 week of curing)you could scratch the surface and start to peel off the poly layer. So no bonding occured. Additionally, the raw fuel test completely failed. After 2 mins. the poly warped, cracked, and was done. The oil, however, fared just fine on the surface.I'm now re- testing the full 2 part system (properly), going to seal it with Polyurethane, and will perform another fuel test.
More to come....
