Interesting Paint Defect

Had a client contact me stating that his paint was "hazed" on his 1992 Toyota Aristo (RHD) that he had imported from Japan (twin turbo 2jz) so I asked him to bring it by. His story goes like this - he was getting ready for vacation and hail was in the forecast, so he decided to put "mats" on his car so that it wouldn`t be dented while he was gone. Fast forward 2 weeks and he returns from his trip, takes the mats off, and sees this -

Trunk -



Roof -


He claims the mats were in the same place when he returned. Paint readings were very good (220µm) and there was no deviation over the defects. Can`t really tell in the photos, but the clear was not affected in the slightest, just the basecoat. I had never seen anything like this before and he mentioned wrapping the trunk, roof, and hood (no defects like this on the hood) instead of repainting.
 
We`ve seen this before on the forum from putting non-breathing covers of various types on the paint, some sort of moisture penetration. I can`t remember what the recovery has been in the past.
 
Interesting thoughts......wonder if there is a way to remove the moisture and seal the paint so that it doesn`t happen again.

I can tell you that the clear was heavily contaminated (multiple passes with clay kept pulling impurities) and there was no wax, sealant, etc on it. He has had the car for about a year, it sits outside all year long uncovered, and he has never applied anything to it.
 
I can *ALMOST* say that I recall somebody dealing with this by gently heating the panels and thus getting the moisture to dissipate or just letting the sun do it. Almost. I mean...it`s such a weird subject, and the idea of "evaporating the issue out of the paint and away" sounds so nutty that I figure it stuck in my memory just enough to post this...which I realize isn`t of any real help :o

Just did a search regarding moisture trapped and what I have found is that you prep the area with 50/50 alcohol and slowly use a hair dryer to remove the moisture. I`ll have him come back and see what I can do - not like it`s going to hurt to try!

Ah, so there was something after all! Your Search Fu is strong ;)

At least it`s something you can do for him; no loss if unsuccessful but great if it works.
 
Gotta be the same thing happening with water rings on your table. So you would think one can improve the situation, because you can definitely do so with them oin the polyurethane. Isn`t clear coat just a form of polyurethane?

He`s bringing the car back to me regardless, so if I can make it better while it`s in my care, that`s a plus in my book!
 
I`m thinking when this came up in the old days, some guys left it in the sun and it went away, and some no matter what they did, it wouldn`t.
 
Ive had this happen with a hood cover bra thingy. Never cleared up for me on my 2002 Bonneville if I recall right. Keep us posted!
