Oh Woes Cracking Class C

James Writes:

Hi Wade,

We have a 2008 Itasca Navion, Class C motorhome.  I have discovered the gelcoat on the rear of the coach appears to have faded and has small spider web looking cracks running vertically up and down the back of the unit.  I talked to the body shop at the dealer, (Lazy Days RV, Tampa, Fl), where we purchased the motorhome.  I was informed the condition is called “Checking” of the Gelcoat from sun damage.  They advised the gelcoat could be sanded and repainted, but no guarantee it would last more that a couple of years.  They believed the damage was just aesthetic and no leaking was occurring.  Will any of your products help me?

 Welcome to the world of frustrating RV finishes!  Or RV Finish Restorer with Wax will bring back the shine but will do nothing to help the cracks or checking.  The dealer is correct that checking is caused by sun and heat.  My guess is your rear panel is a FRP material and not a molded fiberglass cap. The  FRP used on your rig is more of a plastic with a high gloss jell coat type finish on top.  Replacing the panel is the only way to properly fix this eyesore as it will be imposable to fill in and stop the cracking.
