help!? Fiberglass puckers on back corner of travel trailer

Hi guys!
I have a fiberglass 2015 keystone passport. The rear left exterior corner has a wavey (bubbled?) section at the corner. I have included a picture. I found some small areas that needed silcone at the corner. I have already siliconed that entire corner (the picture looks like there's a gap but it is filled with silicone). I am preparing it to sell. Can anything be done? Hope the picture helps you guys. Hoping something can be done about the bubbling/wavey area. Thanks very much as always!

That's delamination from water intrusion. Unfortunately it will require replacement to make it "new again".

What flybouy said. Also, silicone isn't the best option to seal the exterior of a camper. The roof joint should also be inspected.

Hi 08quadrum,
Thanks, 2 questions: what would you use besides silicone? Also do you mean just the top corner of the roof joint, or the whole rear top edge? thank you!

Make sure that clearance light above in your picture is sealed. It's very common for them to develop a leak.

Proflex, made for RVs and will stick to itself unlike silicone.

pro flex

Just checked the Co. web site and found that they do not recommend using their product on TPO or EPDM.

You may not have a delam problem. We have a 2014 Laredo 5th wheel which has some puckers on the back outside wall (not quite as bad as yours though). I have read several threads that said that keystone builds their back walls floating (non laminated) because most of the wiring is back there.
