Insulating under rear quarter panels?

[beast1210]

So I'm repairing the cancer in the Scout, while I'm in the rear quarter panels it occurs to me I could put insulation in there before I close it up. I have intensions of insulating my canopy, and was going to make a removal floor from the pink sheathing. Not wanting to deal with a mess of expand a foam to cleanup inside at a later date. I thought the pink sheathing would work here also. What do you guys think, will it work? Or just a waste of time.

pink sheathing

I have plenty of space in depth

Something like this, my hope is leaving the bed area clear for regular loads and not decreasing my area back there

i would just use an extra blanket

My HO...

IMHO I would go the closed cell (low expansion) foam. Before anything, remove as much rust as possible, treat the metal (IE etch prime or whatnot...) and then get some cans of the DIY spray on bed liner in a can (Wally world). Then, once it has all been done, use the closed cell foam to fill it all in. It will insulate better and provide sound deadening...And may even give a little more structure to your scout..Just my idea...

Just remember that no matter how you insulate, there has to be good drainage for condensate

expanding foam

If you don't want to deal with the mess of cleaning off/out/up expandable foam, one remedy is to put it in a plastic bag first. A garbage bag, grocery bag, etc, a bag that is the appropriate size. The foam expands to fill the contours of the space but is still within the bag. What you end up with after the foam dries and hardens is a piece of foam that fits perfectly and can be removed with no problem.

It's a technique that is sometimes used in packaging and shipping. Put the object to be shipped in a box, wrap it with a couple bags, inject foam into the bags, viola'.... afterwards the object has a foam encasement that can easily be removed and is form fitting.

It's a good technique to use for insulating. I was set on injecting my quarter panels this way but decided to insulate the inside of the bed in case I want to cut the quarters in the future.

X eleventeen on allowing for condensation drainage.


For inside of the 1/4's I'd look into the insulation's used by hot rodders etc. Most are for noise, but some are for thermal too.

Are you familiar with the various moisture curing polyurethane paints like POR-15 or Rust Bullet? There are commercial such paints, but those two and their like are the easiest for the home hobbyist to get. Given how Scouts and all IH's rust like that is their primary function in life I would invest heavily in a paint of this type for all of those hard to reach nooks and crannies.

This Scout II has about 15 gallons of POR on it. I'm serious, all of the black visible is POR or POR that has been top coated. The owner is just a tiny bit anal.....

btw, that Scout is known as the "Harvester of Sorrow" or "Harvey" for short.

Great idea, just not sure the plastic would hold over time

I have to get more por-15, mine dried up from my axle project. "Harvester of Sorrow" same as Hoss in seattle?
