Hi, does anyone here have any experience using Scotch-weld? Looks like it's a structural adhesive. They have so many different variations (adhesives, epoxies, etc). Part of my floorpan broke through and I'd like to attach a new piece, but with no welding equipment, I'll have a difficult time doing this. However, scotch-weld caught my eye.

 

I know others have tried this same thing....Since these cars are unibody the floorpan is part of the structural strength of the car--using glue to hold metal in place will get you a floorpan but not structural integrity you need.
You should be able to open the yellow pages (or do a search online) to welding and call a shop. Bring the car in along with your sheetmetal and they should be able to weld a piece in there for you. I wouldnt think it would be very expensive either.

 

Thanks for the reply. I know when I asked maaco a while ago, they wanted $320. Never went back lol. I was just hoping an epoxy with a high shear strength would get the job done :\

I'm guessing the floorpan was weakened, to begin with, due to the lack of SFC connectors. If I install SFC connectors, would that take quite a bit of load off the floorpan then?

 

3M also makes autobody structural adhesive... The same kind of stuff now used in factories around the world (Porsche, Lambo I think). But it requires a special applicator "caulk" gun that's also a small chunk of change. I plan on using the Automix system on my quarter panel, since I am also in the same boat with no welding supplies (or the money or electrical service for them in the garage).

Oh, and SFCs are a good idea to tighten up the body a bit... Going to do those at the same time since body flex has already cracked the lower driver's corner of my windshield .

 

We use Crest panel bond...its the same type of glue that bonds the tiles to the outside of space shuttles.
If its a small patch on the floor it would be acceptable to use glue.If the floor pan needs to be replaced you will need to weld it.

 

My dad and I used that stuff to hang new skins on his F150 truck bed. That stuff is strong. It wasn't cheap though.

 

Haha. Yeah. $45 on eBay right now, plus another at least $60 for the gun... I'm planning on also getting the seam sealer that comes with the gun for $75 (so I don't have to buy the gun separate).

 

It's close to a 1x1 (foot) hole. If glue + SFC connectors (which I already have) will be acceptable, then thank god.
