my rv has shinney spots and the rest of the rv is dull. I wanted to restore the shine but was inform that it wasnt posible to restore the shine on fiberglass by waxing or somthing else. There is a guy in my area advertising on craigslist that you can restore the finish. he estimate my rv at a cost of 70 dollars in material and 2 days work at 600 dollars.he guaranted that the shine will come back and he will do a small section first to prove it. can it be restored and if so does anybody know how to restore the shine on fiberglass. money is tight and Im willing to do the work myself if it means saving 600 dollars.
