some colors absorb light more than others? hahahaha nothing!
THis question absolutely cracks me up. I saw someone say they thought it was crappy because of the film it left on the ski.
WTF!!!!! you grind the bases on carpet, metal rails, pvc pipe, lexan plastic, grass, mud, rocks and stones and you are worried about a water soluable film left on the skis?
No, there is nothing to worry about as far as the residue is concerned.
