Dear Dan,
I need to tell you (and for the collective) my story (lesson) about my experiences. (Thanks God, only the nose got these coats, as follows:
1. Stabilizing paint of thinned LY 5052 epoxy, right onto the bluefoam.
2. Next day, I sanded with 280-320 grade wet paper to get a brilliant, smooth surface.
3. I covered with 1 layer of 2/3 oz glass, with thinned LY5052, After hardened, I slightly sanded.
4. I covered with 1 more layer of 2/3 oz glass, with thinned LY5052. After hardened, I slightly sanded again, the surface became superior quality, and strong enough to bear the engine bank, tank, undercarriage, etc. Without long, hardwood spars...
I got waterbase acrylic hard floor lacquer, colored it to yellow, and sprayed on.
And sprayed on 2-component transparent polyurethane floor lacquer, just like before, for 50 years...
After several months, some vertical ripping appeared below the tanking/overflow tubes...
Next year appeared the foam, covered by the glass, in half centimeter wide strip...
Ripping and stripes, more and more...
Finally, I put this complete nose into Polyethylene sack, fill with methanol, and after a week, I simply scratched everything from above the epoxied glass surface, by a bankcard. And paint with 2-component yellow polyurethane, and 2-component acrylic auto-lacquer on the top.
Istvan,
