John, in Oklahoma in 100 degree heat Lizard Skin by itself is not the ticket for heat control. That is also true for the B-Quiet. However, put em together and you've got something. The "mylar bubble wrap" stuff is also not very helpfull at that temp. Maybe you and Vern could live with it where you are, but not here. I do not understand how the foil works to the inside, but my tests showed it to work best that way, unless it was in direct contact with the rays of the sun. Joe

 

The brackets (guess they are called brackets???) that hold the stock lower door seals in place were rusted away in my truck so I glued a piece of deck lid rubber from my donor car in their place. It seems to be working okay. There is not much you can do about that open hole in the front sides. I painted that area with POR-15 so I hope the rust doesn't come back soon. I gave some thought to using foam too but decided against it...

 

Thanks Vern, sorry I didn't explain myself better in the last post. I was at work on my break with a half dozen things on my mind.

 

An update on Lizard Skin or Cool Car Ceramics ceramic spray on insulation. As I noted previously I used these on my 40 coupe. This weekend a friend came by with an expensive tester that measures coating thickness in mils. His brother is in the paint shop supply business and had it as a sample. He had used it find out when he got to 40 mils applied to his truck. He rolled on three coats to get to 40 mil. We used it to test the thickness on my 40. On the inside that was sprayed by a local body shop that does it regularly it varies from 10 to 20 mils, on the underside that I sprayed it is about the same. The shop used 2, 2 gallon buckets to do the inside, top to bottom, side to side. I used about 3/4's of a 2 gallon bucket underneath. Didn't get close to their recommended 40 mils. At least the floor has a coat on each side. I am contemplating using what I have left to put another coat on the underside of the roof. Although it would be applied to the B-Quiet I have installed already. Not sure what I will do there. Anyway, FYI 40 mils is much thicker than I would have thought. I don't know how you would know for sure without a gauge. Joe

 

Thanks for the update, Joe. That info is helpful.

Still thinking about the possibilities....

 

The foil on the insulation is vapor barrier. In building construction it should go on the warm in winter side of the insulation. It kind of depends on which side of the mason/dixon line you are on.
However, if my memory serves me right the Big 3 automakers put a poly vapor barrier on the inside surface of the doors. This keeps the water vapor from getting inside the door.
