: Filling rust holes around windshield

I'm about to have my windshield replaced and I want to repair the sealing surface while the windshield is out.

I was thinking of the POR-15 Floorpan repair kit, but $120 is a bit much.

Does anyone have a suggestion for effectively filling these leaky spots?

Hey cj, what I did to repair a rusted out window channel was to first cut out the rust, second was to sandblast the area, and then third was cut out metal patches from scap, cut to size, then using some of that 3M two part epoxy (got it and the special dispensor from a friend that ownes a body shop) glued the patches in using sheet metal screws to hold everything together until the glue dried. I had to drill the screws out that had glue on them same as if they were welded in. Ground down any excess glue then used duraglass to fix the low spots, primed it all followed by paint and reinstalled the glass with urethene. No leaks and you can't tell it ever happened. The epoxy is the stuff used on door panels and real small quarter panels. I can find the name if you like. Sure beat pulling the heater core and defroster duct which I would of had to do if I tried welding in patches.

Thanks, Tom. I have some Devcon two part epoxy that we use at work to put stainless inventory control tags on equipment. You have to grind those tags off, so I'm sure this will do the trick. This is on a drilling rig where everything is subjected to a highly corrosive environment and lots of vibration.

One part is blue and the other part is clear. When mixed sufficiently the whole thing goes clear. Does this sound similar to the epoxy you're talking about?

The name of the stuff is Duramix 4176 and is made by Polymer Engineering Corporation in Oxnard CA and their number is 800-537-9204. This stuff is black and white and uses a special dispenser to mix the two parts together equally. The stuff you're talking about should work also!
