Welding vs. Glueing

[tim21391]

went to local part store to look for this special type of bondo i use at the body shop i work with... not sure the name we call it marr glass... but its dark green and it has kevlar in it... and the ppl at autozone said to glue my cab corners in because the project starts in about 2-3 weeks... anybody ever tryed that???

[bad6772]

I use glue almost every week......Its a great product.....But for something as a cab corner i would just butt weld it....You can glue it , but it would require a over lap type of fitment....

[bigsnookmaster]

I would weld it.I would think metal and glue expand and contract differently.My .02

Those glues work well for some things ,but on a cab corner I would weld it.

[Peter82]

the glues are good because they have a good corrosion protection to them but you have to wipe off the excess glue. also if you leave glue exposed and cover it with plastic body filler (bondo type). when heat is applied to it, it will more then likely expand and you will see the lines in the paint. just but weld it and fill in the pits with body filler.

My experience is certain "metal adheseves" will soften or lose adhesion with heat. I've removed "bonded" pieces with a heat gun (no gloves!)

[bad6772]

I doubt it was a Panel Adheasive...Or Panel Bonder Such as 3m or Kent.....As i said above....Glue has its place....And this in not one of them....And to add what others have said....There is a (ghosting effect) that can and will (over time) come to the surface...Just but weld it......Its the easiest and BEST way........and the RIGHT way

You can doubt what ever you like, the peticular product in this case was Duramix Structural Metal Bond-OEM approved , and I DID remove said repair with less heat than expected.

[tim21391]

cab corners are ordered and on their way.. my buddy of mine is going to let me borrow his 110 mig welder.. and im going to get some bondo soon its heavy duty stuff that has kevlar in it.... so it will be good.... other friend has a cut off wheel so it should be done in a weekend so after thanksgiving ill update you guys...

I would have to see the way it was applied and to what it was applied to comment....I am not saying its not possible....But when done correctly its unlikely .........But what do i know i only do this everyday.

[Gregs67]

I personally do not like leaving an overlapped pocket to catch dust/debris/moisture on any kind of glued panel,.....but I have never used it, so I cannot judge it.

[bad6772]

I agree Greg especially in this case.....

Agreed

what i do is when u tack weld or bead, put some of the green "glue" everywhere the weld isnt, sand the bondo over that and make it smooth

Hey JR, not picking on you but just making sure that any "newbies" on here reading this understand what you mean by "bead".

Never, never, never bead-weld sheetmetal. (1" inch long welds are WAY too much, even welds 1/4" inch long are pushing it) You are just asking for trouble. Put a small stich weld then cool (think of a single stick in sewing), stitch and cool, stitch and cool. Even going slow you will warp it some, but is fixable.

Go slow and you will be fine but run a "bead" and you will warp the crap out of your cab that may not be fixable even with a ton of filler being added! I added a pic to show what I mean by stich welding. This is my cab when I had to fix the fuel hole area.

Richard8971 thats a very nice job

[hdflstf]

Weld it. You want to maintain the structural integrity of the cab.

Jeez ... all this glue talk is gonna put the pop rivet companies out of business.

Weld her up solid!

Inside View. Skip around and weld small stitch/tack welds until it is welded solid and then sand it smooth. Keep the big grinding rock off of it. In some places you will sand through. Stic a bright light behind the weld and you'll see all of the little pin holes. Then I get on the back side and go down through there and touch up each little hole until it is all solid. It has worked better for me to touch it up from the back side when you can. Here's the back side. I will go back and sand it "fairly" smooth too. If you have a gap in the seem when your panel is fitted, then you stick a piece of copper behind the gap and weld it up. The copper trick will save you a lot of grief.
