I doubt that this felt paper is available but I'm going to inquire anyway...... This is the stuff that car manufacturers used between the gas tank and body of the car.
It's felt tar paper, just like roofing paper only heavier. This stuff measures about .080 thick. I've never seen any roofing felt that thick. Maybe there is some supply house that carries it.T

The other is this 1" wide tape. It looks like duct tape but it isn't. Looks like a cross between duct tape and friction tape. It looks like black vinyl on the exposed side with a light cloth adhesive side. I checked McMaster and couldn't come up with a match.

The "felt paper" is probably 50# or 65# roll roofing, same as 90# with no stone. I haven't seen it available in years but I'm sure car restorers have something to sub.

Even on a judged car no one is going to drop the tank to see if you have the correct pad or tape. Use several layers of standard roofing felt. If an edge shows, use spray adhesive (contact cement) between the layers then trim the edge with a razor. You won't be able tell if it's one layer or five layers.

Two, or even three, layers of 30# roofing felt should be an acceptable substitute. You can fuse the layers together with a heatgun. Or an iron both sides are mylar covered. Heavy duty duct tape will probably work, but you will need to cut it to width

This is a crazy item to find. It was used in a lot of places on old cars but it sure is hard to find. I really have been looking for what I know it is but it's not showing up.

With restorations being so popular you would think it to be common. I'll be curious where it might be found.

It is not felt roofing material. That would hammer itself out in no time.

It's not felt but the good old roll roofing wasn't paper but asphalt & some even had scrim inside which would be ideal. I would not use felt.

90 pound roofing felt (0.100 thick)

gaffers tape (high tack, vinyl back)

You won't be able tell if it's one layer or five layers.I realize that no one is going to look under there, but it is the ideal material for the application. It's not abrasive and it doesn't hold moisture.
I figured it would be tough to find a substitute and I've never seen #90 wt. so I had thought of gluing a couple layers of #30 together with perhaps some rubberized spray undercoating. As far as the tape, I have some 1" duct tape but you know what happens to duct tape after it dries out.
I found that gaffers tape at MCMasters but I don't really know what the stuff is.
Thanks to all for the help and research.

Use ice & water schield in 36", & 6" for around winows but it's very sticky on one side but look at it I think it's what you want.

You can by it with no grit, W.R. Grace brand & I'm sure others are smooth also.

<<snip>> but I don't really know what the stuff is.

Gaffers tap is used by the electricians and sound people on movie and theater sets. It's really sticky, but doesn't dry out so that it can be cleanly removed when it comes time to change the set - sometimes hours later, sometimes months later. I've had some in place in the house coming up on 15 years and its still holding on.

Also, just Google "90 pound roofing felt", its available lots of places, around $40 for a 3 ft by 33ft roll (probably a lifetime supply for you).

How about the tape used by auto glass shops to mount glass in side window channels,as per vent windows and the steel channel that lowers door windows.It shood be avalable at any glass shop that does auto glass.

Did you try calling them and asking? Sometimes they can come up with things that are not in the catalog.

Don't know if it's still available but that felt material looks like what was used on the perimeter of concrete floor pours.

FWIW, I installed an aux. fuel tank(20 gal) on my 1979 Chevy PU when it was new. It was a take off from a wrecking yard truck and was a duplicate of the 79's OEM tank. I used 2 layers of 30# roofing felt between the tank brackets and the tank because it looked just like what the factory had used. Never had a problem with it and I drove the truck for 20 yrs.
