Should I first use primer after sanding then grip?** A: I am not a body expert but I did my ARE fiberglass tonneau cover with the raptor on the exterior. I sanded with 120 discs and them wiped down with denatured alcohol. I did not have prep cleaner. Six months later it is still looking like I just sprayed it. I hope that helps. I'm sure the are body people who will say different. **Q: Just curious if this is transparent? Gonna spray this over some plastic chrome** A: According to their MSDS, it's just solvents: toluene 40-63%, acetone5-23%, less than 5% xylene and ethylbenzene. Bulldog is made of much more. Toluene 15.0 -40.0 % , Methyl ethyl ketone 10.0 -30.0%, Butyl acetate 10.0 -30.0%, Xylene 10.0 -30.0%, Divinyl benzene 1.0 -5.0%, Styrene 1.0 -5.0%, Ethyl methacrylate 1.0 -5.0%, Ethylbenzene 0.1 -1.0 % Ethanol, 2-Butoxy- 1.0 -5.0 % check that out...remember the Divinyls? **Q: Doss this raptor upol expire if havent used it yet? Cant fi d no exp date on it** A: as far as I know it does not expire. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Does help the paint adhere to plastic surfaces. *by B***E on 5 October 2025* Worked well to help paid adhere to the plastic.
