Developing Crack in Sidewall

One of the sharp technicians at the local RV shop showed me that my sidewall had some repair done from a previous mishap. There is a crack developing and he suggested either covering it with clear tape or some silicone type material. He said that rain water would get behind it and ruin the siding.


Before I run out to the hardware/rv shop, what are you folks experience and advice on this please?

Sounds to me that the repair was done improperly & the crack is developing due to stress. Tape, of any form will not fix it. Post some photos so we can get a better idea of your issue.

Is that a crack in metal or is it a crack in bondo?

If the crack is in the metal, (and maybe even if the crack is in body filler) something is going on. Bent frame? Failing frame?

Upon a second look, I can't tell where the crack is. I was assuming in the back quarter area, ant I was thinking the crack was a couple feet long. But I am not sure now.

Ok, it is a motorhome. I read Land yacht and failed to pickup on the fact that it was under the heading motorhome. I was thinking that this was a trailer that someone had painted.

I knew that aluminum wouldn't crack in such a jagged manner.

Since that is fiberglass, my bet is that this is the reemergence of a poorly repaired previous crack that was caused by an accident.

I am guessing that the repair was mainly an overlay that did not go deep enough or wide enough into the parent material.

Using a grinder aggressively for a fiberglass repair is distasteful but absolutely necessary. .

J. Morgan, from what the sharp tech told me, it is exactly as you describe. So I think you're recommending taking it to my friendly, neighborhood RV shop and have them rework this, right?

Or someone who has done a lot of fiberglass repair on fiberglass.

There are primarily two kind of auto re finishers who know fiberglass, those who work on old Corvettes, and those who work on big trucks.

Both are in demand and both are usually expensive, but as a rule a truck guy would be the cheaper of the two.

An RV shop could do the job if the tech knows fiberglass.

Basically it all comes down to the skill of the individual doing the work. This is very hard to gauge as a poor repair might take years to surface.

Also consider a place that repairs boats, lots of fiberglass in boat hulls. Don't know if they would be more or less expensive then a truck place.
