Was it the Restore and Wax product you tried? or the actual full strength compound? The Restore and Wax works will if only using a micro fiber cloth if you are dealing only with light
surface stains - such as black window streaks or bug stains. Either way on a badly neglected and stained fiberglass either product works best using a wool bonnet on a power duffer, not to mention it makes the job go way faster as well.
The good news is you will only need to use the power duffer once if you do it right the first time using the correct product. Haven't had to use the power buff on mine in 7 years once I got the shine back. Simple wax the trailer 2x a year using a cloth now to keep it shining.
