Fiberglass parts are easily fixed and it is not at all uncommon for the fiberglass parts to need some fixing before final fitting and painting. I know that on my RV-10 wingtips, I had to split the trailing edge on both tips in order to get it lined up straight with the ailerons and flaps. One side was also about 1/2" too long on the trailing edge. You may find some pillowing or dips in the skins of the tips after you get them fitted so fix those also. You don't want them acting as a trim tab.
