I have a buddy getting ready for paint on his carbon cub, and for weight reduction he wants to take it thru polyspray silver and call it done. I told him I'd check in with those of you who have done this on your Kitfox and I'd like to see how this setup has held up for you over the years . I have several coats of polytone on my Series 5 and its held up very well for 20 years so far, just want to see if stopping at the polyspray coat will give similar results. Thanks guys, Bruce N199CL
