I am planning to do the final spraying of my Kolb fabric with Poly-spray and the color coat (Nevada Silver) this week. Anyone else use this silver?
The number of UV cross coats can be less, right? I think I will use two cross coats of Poly-spray and two cross coats of Poly-tone.
Any thoughts anyone?
So good to see the VW pioneer Rick Neilsen and Craig Spoke at EAA. Looking forward to Naugua Fly-in.

Bob,
One thing I noticed on my Cessna, which sat on the ramp most of it's life, was how much the TOP of the wings and upper surfaces showed fading, oxidation, and weathering in general. Direct sunlight is BRUTAL!!! However, the undersides of everything else, even though the paint job was 8+ years old, looked pristine, had no oxidation at all, and otherwise 'good as new'.
So!!! Considering the underside of your plane (and mine) will virtually never see direct sunlight, I only used one layer of Poly Spray on the underside of the wings. On my spraying job, I found I could STILL see a little bit of daylight with the two top coats of Poly Spray, so I opted to go ahead and spray three of the Poly Spray on the topside surfaces only, and IIRC, I used two coats of Glacier White on the entire plane.
Therefore, I would say I ended up with three 'top coats' of Poly Spray, and one underside coat. Everywhere then got two color coats of white. Since it's a hellava lot of work and money to recover the wings, I don't think I'd be inclined to skimp on the sunblocking Poly Spray. Maybe that's just me.
FWIW, Mike

the book says 3 cross coats will stop the uv. if you use 2 cross coats of
silver,, you may not stop all the uv.

I think you will be ok with your plan. The silver color coat will reflect well.

Great to meet you. I sprayed the silver UV coating two on the top (sunny side) and one coat underside on my plane then tried to spray Red. Did not work well. Learned later that I should have sprayed a white coat then red. Your results may vary depending on your color.

Bob, Read Appendix A of the Poly Fiber manual. Nevada Silver, Rancho Silver, and Piper Trainer Blue have all the aluminum powder in them that Poly Spray has and you don't need to use Poly Spray at all.

Page 94 of the Poly Fiber manual Rev 21 says:
"If you can live with a silver or blue plane, skip the three cross-coats of PolySpray and use three coats of 220M Nevada Silver, 222M Rancho Silver or 318M Piper Trainer Blue top coat paint. These three colors have the same aluminum pigment as PolySpray and will give your ultralight fabric full UV protection."
What is not clear to me is whether they need to be cross-coats (six total), or finish coats (three total)? I would give the distributor a call; they should be happy to help. Let us know what they say.
I imagine a max of three cross-coats of anything-UV is quite enough. And since you would apply only three, make it three of your finish color, and don't apply any PolySpray at all.
Are you weighing your plane before and after painting? It would be interesting to know the weight of the paint. In fact, I plan to weigh all throughout the construction of my plane (when I finally get it) so I'll know weights of just about everything.
