Good Morning To All! Just a Quick question. Has anyone ever used the aftermarket fiberglass bumper fillers for our car? They constantly are on Ebay. I was wondering about the quality of the finish, fit, and if any modifications need to be done to the cars. These part come gel coate in black from my understanding. Are the gel coated or in black primer? Just wanted to ask these questions from someone other than the manufactuer. Thanks in advance and have a great day!
