8mm foam butyl?

One of those autoglass installer places? Speedy Autoglass?

NAPA, any autobody supply house, comes in a caulking gun tube, or "tape roll". Tape roll 5/16" x 15' Napa part number MMM08621 $8.49. Caulking tube style easier to use, tape requires channel to be thoroughly cleaned of all residue, the tube version is "self leveling", and has a ton of other uses.

Don't get it on anything you don't want it on. I have stuck large chrome pieces of trim, like the pieces at the bottom of the rear pillar post in a '65 Falcon Futura with the stuff, almost

That's why I don't want to use the caulking gun stuff. Too messy if it gets on any thing. I intend to use my mini-dremel to thoroughly clean the channel before using the butyl tape. I tried the local Kragen and they didn't have it. There is a Pep Boys a few miles away and a NAPA up in Santee I think.

Thanks for the suggesti>> In replacing the rear windshield of my F150 the installations

If you use the dremel and it takes the paint off, make sure you primer the channel and then a coat of paint of the same type on the vehicle now or you'll have rust in the frame area.

Thanks but I have a ton of soft brush attachments that shouldn't damage the frame/channel at all. I finally found some at a local galls shop used by the closest Ford dealer and they sell it cheaper than NAPA's
