Weathering Fiberglass Problem

    My motorhome is a Class C Tioga with a fiberglass exterior.  The fiberglass that forms the roof over the upper bed ares is becoming quite weathered.  The fiberglass roof area is a "dull surface", almost like a powdery surface. I have tried rubbing in a high quality fiberglass wax, this helps but does not last very long.  The dullness comes back in a relatively short period of time.  

    I am looking for recommendations as to how to repair this surface; is there a clear liquid that I can apply to help protect the fiberglass roof surface?  I would prefer to find a quality product that I can apply to the surface.

    Thank You Kindly

    Dennis

    The Poli Glow product should do the trick for you.  I have seen It's results on badly oxidized boats, and it is amazing.  Motor home owners who have used it have praised it on other forums.  It is available as a kit from both the manufacturer and through Amazon for $74.95.  Multiple coats are required, so it involves a bit of work.  Google Poli Glow, and you should find plenty of testimonials.

    Fibre Glass finish is similar to that on boats (fibre glass and gelcoat).

    The dullness and chalky surface is oxidization from UV Rays.

    Wax is only covering the problem and not getting to the root of the issue.

    You need to first apply a mild Compound to remove the oxidization, and then apply the wax.

    Depending on how bad the oxidization is, will determine how heavy a Compound you will need to apply.

    Best results come with the use of an electric buffer and a spray bottle (water).

    After 25 years of boating, I can tell you waxing is never a fun task! 

    Hire an RV detailer @ $10.00/ft. and let them do the heavy work.
