Replying to Polymer Science People

My skis are pretty beat up and I decided to refinish the top last year to see if I could eliminate some of the scratches n' such.  I coated them with a thin layer of Polyester  2 part resin, the kind where you add Methylethylketoneperoxide  (MEKP) to the liquid to the contents to harden the compound.  Its commonly used for surfboards and hockey stick so i figured it would work.  The stuff cracked though all along the ski probably due to the flex and cold so it looked like shit and I had to sand it off which was a pain.

Does anyone know of a clear polymer that I can use to coat the tops of my skis?

Where can I get it?

Tips?
