How Our Process Works

We start by cleaning and assessing the damaged area to determine whether the crack runs deep into the laminate or affects only the gel coat surface. You'll see us grind out compromised material, creating a clean bonding surface that accepts resin layers without trapped air or weak spots that could fail later.


Our technicians at Brendel's Collision & Paint apply multiple layers of fiberglass mat and resin, building thickness gradually to match the original panel strength. We use reinforced resins and high-strength fillers to rebuild surface structure and prepare for smooth refinishing.


Once cured, we sand and shape the repair to match surrounding contours, then prime and paint the area for a seamless finish. This method works on trucks, RVs, boats, and specialty vehicles common throughout the region, ensuring your equipment stays functional and looks sharp.
