Lookin' good Henry.

I wonder how much the stuff helps noise-wise in a topless roadster?
I'll probably do it to keep the heat down . . . from the engine and exhaust anyway . . . there's always the Arizona sun to contend with.


Anyhoo, a small comment that's not too far afield.

My pal - who runs a full fendered mit/top 29 A roadster stuck some of that expanding foam stuff from a spray-type can into the doors.
Quieted them down quite a bit.
Not too many other places where you could use the stuff.
Interesting nevertheless.

Kinda makes me wonder how it would work out if you glued regular white insulating foam boards to the vertical surfaces, kick panels, quarter panel sides etc.
The white foam boards did a remarkably good job insulating my roll-up garage door panels.
Both in winter and summer.
1 1/2" thick fwiw, but 1/2" would work ok in a car I think.

There are kits for insulating these doors, but cutting standard 4' x 8' sheets of the stuff with a razor knife/box cutter and a drywall square as well as snapping a line on the longish cuts is easy.
Cut em wide enough so they'll snap into place and no adhesive needed.
