My Fiancée's father just gave us his old camper. The original owner must have had decals on the trailer and then removed them after a few years but now you can see the lines where the paint has faded around the decals. Someone told me that if this is a single stage paint than I can use a product like Meguiars #7 to restore the paint. What kind of paint is used on these trailers? Is a gelcoat? I need to know so I can figure out how to go about restoring the paint to a like new finish again. Any and all help is much appreciated!
