I get that sometimes on reskims myself,but if you ever use the same stuff on boards no problem.
It sometimes pulls of high spots and such like,just keep a little gear by and wet up and put on problem area thats all you can do mate.
its rarely the product mate and nearly always how you apply or background problems etc ,happens to even the best in the business!!!!
if im using board finnish on reskims i always use a lot more water /spray than on boards it seems to help this
