Mike2338 Posted February 14, 2017 Report Share Posted February 14, 2017 My 5th wheel has partial paint without clearcoat. Could have added clearcoat at time of purchase but decided not to. The gelcoat in spots is starting to fog and the paint has surface scratches. I am researching different polishing compounds and processes and would like to get some opinions from you. I will probably be buying a porter cable 7424XP polisher. It has received good reviews and I will also use it on the truck and to rub out some surface scratches on the Corian countertop in the coach. My confusion comes in which compounds to use. I am looking at the Meguiar's M4965 Marine/RV Fiberglass Restoration System but my concern is can I use it on the paint portion or just the Gelcoat? Should I use a car finish system like Meguiar Ultimate Compound and Polish Combo? Or something even more aggressive? Thanks Mike Link to comment Share on other sites More sharing options...
rpsinc Posted February 14, 2017 Report Share Posted February 14, 2017 My experience tells me that any product will be different for painted parts and for gelcoat parts. I am working on the same type of thing and have 2 products. I dont trust Meguiars since it was sold and the formulas were changed. They dont seem to perform as they used to. I have some product that is working well made by 3D and for the painted parts using their #426. Marcel Link to comment Share on other sites More sharing options...
