Paint Checking/Spider Web Cracks

[Busskipper]

OK - I've gone on the WWW and reading all that is out there on the tiny cracks that occur in the dark paint of many Motor Homes.

My Question is - Has anyone found a Wax/Polymer, that does not turn white so you see the little cracks in the light?

I've cleaned - buffed - played with - this a lot and if I could just find a way to make it shinny with out the cracks getting "white" i honestly think I might not really notice them.

I mean seriously these things are what I'll call 2' er's - step back to 4 feet you never see them but step up close and search they are everywhere.

I'm sure someone on the forum has a secret cure.

TIA,

There are some waxes/polishes designed for darker colors. I have read where some folks use those and they hide the crazing pretty well.

I use Dri Wash 'n Gard...easy, lasts, no white. 😉

I really don't want to get into HOW or WHY it happened - It's there, and unless you are 2 feet from the Coach you will not see it. So there is no chance I will spend the $10,000 it would cost to repaint or repair.

But I appreciate all the Fact's, just am looking for the simple solution.

Thanks again,

I think that might be the answer - "Pledge" but the problem is it is an oil and will not do the same as a Polish. but I am going to give it a try.

When I had a Boat Company the pre guys used to use pledge all the time - would really make the Boat look "Good" problem is that a week later it was in need of more Pledge.

Thanks, for the suggestion,

I had this problem with my previous coach but they never left any reside from waxing or cleaning. What I was told is that the darker colors absorb more heat and was more susceptible to crazing due to thermal expansion/contraction. Nothing to do with the fiberglass and even the quality of the paint. Just age, sun and heat.

Unless you nose was right up to the coach they are virtually undetectable.

There was some bad stuff but you find the crazing on just about any coach and it will be in the darker colors. If you use a infrared thermometer, you can see as much as 110 degrees difference between a light color and a dark color on the same coach.

My coach was built in August 2001 and I am beginning to see the crazing in the darker trim colors, the light tan is fine.

It was definitely the fiberglass that was not properly cured. Country Coach had a lawsuit against their supplier, but went bankrupt before owners got anything out of the lawsuit. Fiberglass was not cured properly, and started checking. The dark colors makes the fiberglass hotter, and checking results. The panels can be sanded smooth, and checking will probably not recur if light colors are used when repainting.

It was actually bad fiberglass from Owens Fiberglass from about 2003-2007 used on a lot of rvs

The way I read the question is he is simply looking for a wax that will not leave a white residue in the small cracks. Not looking to replace the side walls.
Once my car or rv is clean I simply use a spray on wax. I think the one I'm using now is Mothers show time.

Unfortunately jerry is right. Only fix is to replace and on most RVS that is not possinle. Can replace on hung wall construction, but not on vacubonded walls. Refinish and paint is only temporary because it is still the same panel and will come back.

In many cases it is the fiberglass causing the problem. Not cured properly.
Only fix is to replace the panel.
