Gel coat

[Flints AR Mike and Lorrie]

I am starting to see some small[pencil eraser size]chips in the gel coat.I am going to repair them when the weather get warmer but i am wondering what the cause might be?They are not under any seams[getting wet]in fact they are above[inch or two]seams!

Chips are usually caused by something striking the surface, like stones on the road.

These chips are not stone chips.They look as if there was air under the gel coat,but it took 3 years to show up.

flints, what part of the country do you live in or better yet store the coach in during winter?

Sounds like you are describing blistering. More common in boats than RV as it is caused by water intrusion into the fiberglass. My first guess would be stone chips, but if they just showed up after 3 years I may start thinking something else. If it looks like they were small bubbles that popped, then I would first try and rule outt blistering. A good local fiberglass shop could look at it and tell.

I live in the notheast[Ma]and store the rv in a car port.When you pull off the loose piece of gel coat you can see the fiberglass under it.The spots are in very random areas.

Is the RV exposed to road salt in the winter? Just another possible cause.

You may want to check your warrenty information. I know on my last 2 trailers I had a longer warrenty on the fiberglass exterior than the standard 1 year warrenty on the trailer.

[Flints AR Mike and Lorrie]

It was exposed to road salt once[2 years ago].I am going to sent some pitchures to Alfa to see what they say.

Hello Flints, I am new to this group and have been looking for others who have a similar problem to mine.
We have a 2002 Winnebago which we bought used in Sping of 2006. It had 8,230 miles and no blisters. They start out barely perceptible and then grow to approx 1/4 inch or less. They gradualy fall off leaving a dimple in the raw fiberglass.
I would be interested in your progress toward prevention and repair. Thanks in advance. Dick and Nancy
