Ok first of all i know fiberglass repair is time extensive because of the time it consumes but i rather try it because either i'll lose money.

i bought an aftermarket rear lip for my car. its made of fiberglass. so the basic shape of the lip is good but on one side, the lip on the end starts to come down instead of lining flush with the bumper. since it s made of fiberglass anyone know how to fix it to make it straight. i know that it wato fix it before i toss it and buy an OEM piece.

BTW this is for my wrx and not honda.
