Greetings from sunny Canada!
I would like to lean on your collective wisdom if I may. I have a 2012 trailer that developed a bulge in its side that is approximately 40" x 3". I'm thinking (and might be totally wrong) that wood within an aluminum frame tube swelled and pushed the aluminum against the outer and inner trailer wall creating the deformation. I'm not able to push the deformation in, it's completely hard. This might even just be a wooden support member, I'm guessing aluminum.
Anyway, do you think a repair would be worthwhile? I was thinking of cutting out the fibreglass, taking out and replacing whatever was pushing out my trailer wall and making new the fibreglass repair.
If so, and potentially no access to the back of the repair (the inside wood panel wall also has the same deformation) would you put filler on the styrene insulation and then build on that with cloth and then mat fibreglass? I would like any repair to be as strong as possible, especially as this is the slide side of the trailer. I'm hoping with taking the damaged support piece out my inside panel wall might be able to be pushed back in. Has anyone dealt with anything similar to this?
Any words of wisdom or guidance would be greatly appreciated or even hypothetically how one would go about such a repair. Thank you if you read this far!
