I know that Brian from Gbody parts dot com has discussed the different types of fillers available from his company. I couldn't find the thread so I started this one. Anywho, the thread discussed the different fillers available including the OEM repros and the gel coated glass ones. After reading all about the pro vs. cons of the available fillers, I decided to try the gel coated glass ones. I performed a dry fit in place and drilled holes before having them painted by a local body guy. He only charged me 75 dollars to finish and paint them. I removed the bumper AGAIN today to do the install and was very happy with the results! Anyone else here use the gel coated glass ones in the front? My rear fillers have cracks but are still holding on. I'm thinking that I will replace those next year. Might go for the OEM repros in the back since they are longer. Any advice on the rear fillers?
