Internal sealant/heat barrier

[FullStop]

My wife and I are finishing up the demo side of what will be a complete overhaul on a 1965 Overlander. We're down to just the skin and the frame, which means it's time to start ordering everything we're going to need for putting this together. I know there are several sealants that can be used along the seams and any external access, but has anyone tried using something like Dicor's CoolCoat product or any other sealant/thermal barrier? https://dicorproducts.com/catalog/ro...ucts/coolcoat/

If there's a product out there that's more than just a sealant, I'd love to hear about it. Otherwise, we'll just go with one of the standard sealants and rely on the insulation alone.

Thanks!

We're also looking for replacement axles, if anyone has any suggestions on best places to look, I'd appreciate it. We're hoping to stay with the original torsion design, but use disc brakes, rather than drum.

Yes you would use that on the outside to reflect heat. White is better at reflecting heat than aluminum.

If it's only going to work on the outside, we'll pass, then. I'd rather keep the aluminum exterior. Thanks!

check out the supertherm site. They have numerous products. I used supertherm on the exterior roof of my trailer and it made a big difference in heat loading. My roof was already white yet this made a big difference.

if I had mine stripped the way you do I would use a sealer for all seams etc. and something for heat. I am sure that there is a ceramic type paint that will do what you want.

Not exactly answering your question here, but it's sort of related.

I searched for and found some "high tech" heat sink kind of tape that I wanted to put on the inside face of the ribs to impede heat transfer from the outside skin thru the ribs and onto the interior skin. It was very expensive - don't remember how much - but you could buy it by the the foot and it was going to be a lot of money.

Anyway, I ended up just tearing heavy duty duct tape length wise in 3 equal strips and then sticking it on the ribs - very "low tech" I know . . . and maybe not real effective. I will say that in direct sun you can't, or I couldn't touch the inside face of the bare aluminum ribs - it was like touching a red hot stove element . . . so I felt like I had to try something.

Good luck w/ your project.

Hi Fullstop:
I'm just beginning removing the ply floor on my
65 Overlander and am interested in this thread.
Question: did you consider replacing the wheel
wells to the later plastic ones? If so was there
a reason you could or could not.
Question: Are you re-using the interior or going
custom?
Question: Are you putting in larger tanks?
Thanks

Thanks, BigAl. I'll check into the ceramic paints.
