Paint Checking/Spider Web Cracks

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,
Class A

    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.

    "Busskipper".....wax the bad area, wipe down and then spray with Pledge and wipe again. The Pledge doesn't leave residue.

    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.
