Alright, DIYers and auto body pros, listen up. If you're getting ready to paint, primer, or even just sand a car panel, you NEED a clean surface. That's where Custom Shop Panel Prep comes in. This is a 1-gallon jug of ready-to-use, water-based cleaner and degreaser. Its main job is to cut through all the nasty stuff on a surface—think grease, wax, oil, road film, silicone, and even sanding dust—before you lay down any paint or primer. The formula is low VOC (less than 25 g/l), which is better for you and the environment. It helps eliminate static too, which is a big deal when spraying metallic paints because it helps the flakes lay down evenly and reduces dust attraction. You can use it on primed surfaces, cured paint, bare metal, aluminum, plastic, vinyl, and even leather. Just spray it on, wipe it off with a clean towel (follow the directions!), and it leaves no residue behind. It's a crucial final step in your prep work to prevent fisheyes, adhesion problems, and contamination. Safe for most surfaces except lacquer. Saves you from a costly re-do. Keep a gallon in your shop.
