alright so my car has z3 fenders... thats what was on when i got it, and i completely hate them... im having a bitch of a time trying to find fenders for a price that i would actually want to pay. so i was wondering how difficult it would be to cut out the gills and just fiberglass where i cut out the gills? my uncle is decent with using fiberglass but i wanted some opinions before i asked him

 

i used bondo before i knew about fiberglass

use fiberglasss ... lay a sheet they give you over the holes and lay a think layer of fiberglass over it dont use bondo
