Default fiberglass

k well i just need help ALL the time i guess....i fiberglassed my boat with laminating resin ( 4coats) then i put a coat of finishing resin over, and then sanded the boat down to 220 grit. the boat was looking great BUT i noticed when i roled the boat in the light i could see cosmetic blemishes. ( i couldnt feel the divitos but i could see them when the light hit it right.) so i decided id give another coat of finishing resin and then sand it out....problkem i am having NOW is that i have covered the boat with the finishing resin and now the wax in the finishing resin is really cloging up my 220 gritt sand paper...i guess what i am asking i sanding too much resin off....or am i using the wrong type of sand paper???? or what should i do i mean i spent 2 1/2 hours lastnight sanding with 220 on the finishing resin and i got NO WHERE! i assumed i had to sand the wax off and when i finally got somewhere i AGAIN roled the boat in the light and found that those blemishes were still thier, my other question is do you this the clear coat will cover those up?!?!?!?! WHAT DO I DO!!!! this is a chris craft and i need to be able to have a clear finish to see the wood below.. PLEASE HELP[]

Default RE: fiberglass

Are you using wet & dry sandpaper? Start with 120 or 160 wet & dry, use water. I use dish soap & water, use a sanding block.
Work your way up to 220, then 320, finish with 400. If you don't use a sanding block your hand will follow the dips & blemishes.
