Has anyone done crazing/checking repairs that have held up?
The 2001 MH I bought had sun damaged faded decals with a portion of them sun baked/cracked. I was going to remove them and blend out the ghosting and just repaint the sun faded basement paint.
That was until I saw one section that was obviously getting a lot of sun had a lot of thermal crazing under the dark decals. It is not affected on the plain gelcoat or the light decals. It is the fine spider cracks like alligatoring where you can feel the ridges on the crack. These are traditional fiberglass panels (luan?), not filon.
I want to see if there are success stories on repair out there as opposed to replacing the panels. I can't replace the panels, so it is repair for me, but the scope of what I put into it will be based on the success or lack there of that others have had firsthand. The need to repair isn't to get the best ascetic result or even last a lifetime, but just to seal the cracks and hopefully impede the spread of existing ones.
I have heard what seems to be a couple same stories oft repeated about failed repainting so I'm trying to get an idea on just how large the sample size is of failed repairs before I totally write it off, and the method.
I had little doubt that a simple repaint won't fail over time, but were those jobs just a sand, primer and spray? Or, were they done like hull repairs that do tend to last were they were ground out, resin filled and then primered and sprayed?
I've done similar thermal crack repairs that seemed to hold up on a boat. The other thing is since the glass is perfect everywhere except under dark decals It leads me to believe by repainting in white and using sparingly light color accents I run little risk of developing new cracks. It would really be the repaired areas that give me any doubt after a little searching.
Has anyone forgone repainting and just used white gelcoat resin/ repair to fill the ground out cracks and sanded? Did it last?
The only time I did it was as simple as grinding them out with a dremel and filling and covering with plastic to cure. I have no problem investing the time but it will be hard to know the outcome for a quite a while and if a better option exists.
Btw, I will be doing the paint regardless if it is basement only or full body, so the risk of a failed repair is a lot less than a 15k paint job that develops crazing again in short order. Nonetheless, if there has never been a single properly done crazing repair that hasn't kept at least 80% of the cracks away for several years then I probably won't bother doing much more than grinding and sealing them.
