Bingster Posted March 21, 2015 Report Posted March 21, 2015 I've heard some pretty good things about adhesive for pans and such on a welding site. They are pretty impressed with the strength. They say they're using it for jet aircraft. Eastwood has a kit that is adhesive based for attaching sheet metal. Anybody try this stuff? Quote
Plymouthy Adams Posted March 21, 2015 Report Posted March 21, 2015 it has its place, been used quite a bit of late and getting even more popuar. I have been looking into this and reading viewing films where possible for a certain car I have here...there is one application on that car where the adhesive could be used and do an excellent job, if so would make a very tedious panel repair a lot easier. Virtually eliminate all warping that is common to weld regardless of your best stich efforts. There are a few video's out there that show some of its uses..and usually in large panel this is a combo of adhesive and weld..depends on if structural or not..structural repair still is weld procedure. Pay close attention to the act of flanging metal for repair and also recall in many applications such as door, trunk and hood skins..in combination with this adhesive is folding. Like in welding..the back side is only as good as your ability to seal the joint/seam. I have been told that a majority of tractor trailer cabs are assembled exclusively of this stuff..again..that was just talk about the campfire one night when the subject came up.. Quote
JerseyHarold Posted March 21, 2015 Report Posted March 21, 2015 A friend at work hung the rear quarter panels on his '70 Impala with adhesive a few years ago. It's working fine and is undetectable. Quote
Dave72dt Posted March 21, 2015 Report Posted March 21, 2015 Local body shops have been using it for years. Really speeds up the repair process on rocker panels, works as a sealer against moisture and rust between the panels, however, it will trap moisture just above the sealant ridge, the same as any other caulking material. Applying heat will soften the adhesive so you can get the panel back off. If you don't heat it, the panel will usually tear before the adhesive releases. I haven't used it yet, just what I've seen and been told. I assume it also means being applied to a non rusted surface. Different set times depending on your application so if you need to fold a panel, use a longer set time to allow for folding and adjusting Quote

Auto manufactures have been using panel adhesive for years in production. I just had a friend use it on his glass 32 Chev trunk area where the trunk support had cracked out, fibreglass would not stick but the panel adhesive did the trick. Good stuff when properly used, like most everything. Quote

One thing I'm pretty sure about with pans, they don't sit and fit perfectly. I've never found one that didn't need some help fitting or holding tight against the support structures. They have to be fastened down and pulled into place and much like plug welds or spot welds require a tight, surface to surface contact for best results. I wouldn't depend on just the adhesive to hold them in place. Quote
55 Fargo Posted March 22, 2015 Report Posted March 22, 2015 One thing I'm pretty sure about with pans, they don't sit and fit perfectly.

I wouldn't depend on just the adhesive to hold them in place. With the 2 part epoxy adhesives, and panels that are of a non structural element, they can be clamped down, or possibly screwed down while setting with the adhesive. With the adhesives, you can get a very complete seal and bond on the entire edge of the patch panel, which is a very nice concept. The tensile strength of the bond is incredible too, I think a lot of us have trouble getting our heads wrapped around a bonding agent rather than a fusion with a weld. I did a few patch panels in my cabs floor area using Pro Form panel adhesive, worked like a charm, would not hesitate to use it again. 2 panels bonded with the adhesive would be incredibly strong and well sealed...

Seaside Pete Posted March 22, 2015 Report Posted March 22, 2015 Do you mean stuff like this? Pete Quote
55 Fargo Posted March 22, 2015 Report Posted March 22, 2015 Do you mean stuff like this? Pete A BIG NO, that is a cold weld epoxy, while it has many good uses, it ain't a panel bonding adhesive. This is what I am talking about, http://3mcollision.com/3m-panel-bonding-adhesive-08115.html Quote
50fordtruck Posted March 22, 2015 Report Posted March 22, 2015 I used adhesive bonding for lower door panel repair section and rear quarters 13 years ago and have had no problems. Quote
Plymouthy Adams Posted March 22, 2015 Report Posted March 22, 2015 I used adhesive bonding for lower door panel repair section and rear quarters 13 years ago and have had no problems. Good, a person who has used it for an external panel..in a few bullet statements could you post your prep and step.. thanks.. Quote
Bingster Posted March 22, 2015 Author Report Posted March 22, 2015 Eastwood does have a kit with a flanger and adhesive. If you Google it they do have instructions that show how it's done. Quote
Plymouthy Adams Posted March 22, 2015 Report Posted March 22, 2015 Thanks Bingster..I have watched most all the films..was waiting for a first hand verbal if possible by a used at the home shop level and his findings/experience... Most all the films on you-tube are body shops doing full panel replacement and not doing spot patches like most of these older cars are subject to get. Quote
Young Ed Posted March 22, 2015 Report Posted March 22, 2015 When Dads 2000 GMC 1/2 ton got crashed at a couple years old the guy at the body shop told us the box side was held on strictly with these adhesives. Quote

For first hand information I would reccomend contacting your local body shop supply store they can tell you what panel adhesive is recommemded for and how to prep and safely use it. I'm still old school and still think glue doesn't work but seeing it in action has made me a believer. Quote
40plyrod Posted March 23, 2015 Report Posted March 23, 2015 I've heard of a couple of guys around here using a urethane windshield adhesive to attach panels and flooring. I've used it myself to repair broken plastic parts and stick dissimilar metals together, it's incredibly tough although messy. I can't see why it wouldn't work. Quote
Robert Horne Posted March 23, 2015 Report Posted March 23, 2015 I've heard of a couple of guys around here using a urethane windshield adhesive to attach panels and flooring. I've used it myself to repair broken plastic parts and stick dissimilar metals together, it's incredibly tough although messy. I can't see why it wouldn't work. The urethane windshield adhesive I used worked great on my new glass. I used the remaining adhesive on the headliner insulation, worked great. Once you open the cartridge of adhesive, best to use it soon. You should watch the manufacture date on the cartridge, as the urethane does not have a long shelf life. Quote

Sure it may work, but a 2 part epoxy adhesive designed for panel repair is the way to go if not actually welding. The other adhesives may not have the tensile strength needed in those situations. But for small patch panels on a floor say, why not. These are full framed vehicles not unibodied where those repairs can be structural in nature requiring welding over adhesive or a combo of both, say a 1/4 panel replacement. Quote
40plyrod Posted March 24, 2015 Report Posted March 24, 2015 gotta figure that a lot of the new cars the glued-in windshield is structural to the body and it's strong enough for that. Quote
Plymouthy Adams Posted March 24, 2015 Report Posted March 24, 2015 if the windshield was structural to the body then with body flex it would break at every turn and twist..it is bonded to the body but there are no structural points of contact... Quote
Eneto-55 Posted March 24, 2015 Report Posted March 24, 2015 gotta figure that a lot of the new cars the glued-in windshield is structural to the body and it's strong enough for that. I have heard this before as well, but I don't recall if it was on some sort of official site or not. Quote
