About a year ago I bought a cheap pair of Fisher Atuas. These skis have the common high gloss clear coat on the topsheet that gets scratched up pretty easily. Although the bases of the pair I have were pretty good the tops looked like garbage. After a couple of days and finding I really liked the way they ski I decided to screw around and try to fix the topsheets. Figured I wouldn't make them any worse.
After a couple of failed attempts I went to Home Depot and searched the spray paint isle for something to recoat them. I had tried a few things I had at home but got poor results and after a couple of days skiing the coating started to crack off. The best candidate I could find was Verathane Spar Urethane (exterior). After wetsanding all the old coating off and getting down to a smooth sanded finish I applied the Verathane. At this point I discovered this is a waterbased product. It sprays out really thick and gloppy. My hopes for a good result were pretty low but I finished the one heavy coat and set them in a warm room to dry. It is impossible to apply this stuff in a thin coat or even in what I would call a uniform manner. Checking back in about 30 minutes I discovered the coating had flowed out into a perfectly level coating. I had chosen the semi-gloss as my previous attempts had been with gloss and had not been good. Next morning I checked and the results look factory. Not the shiny gloss but a nice semi-gloss that is perfectly uniform. But will it hold up?
I have had these out at least five times since I did this. I don't ski over my tops very much, nor cross my tails either, but they still look near perfect. Flexing in the cold has not caused any flaking or cracking that I can see. I think it's going to hold up really well.
