I am installing a new Rebel Fuse panel in my '39 Ford. I need to mount the panel on 1" spacers (I'm using 2 each, 1" square tubing, 3" in length) and wish to mount it on the firewall without drilling holes or welding. I have the square tubing and the J B Weld, but, I want to be sure it holds for a long time. It will be a bare metal to bare metal installation. I have checked the archives and it has given me pro's and con's of each, I just don't know which is best or if there is something better. Opinions please. Thank you
I've not used the panel adhesive yet but intend to on a current project.. My experience with JB is good but tends to sag on vertical surfaces.
If this is a bare metal not painted, I would weld stud bolts to the metal this would not generate that much heat and would be a solid life long job. My two cents!
If you do glue it I would drill a few 1/4" holes in the back of the spacers that will go against the fire wall. This will give a "Key Hole" for the adhesive to grip into and on the fire wall use some 36 grit in the glue area for good grip. But stud welding is a better life long way to go! Kevin LFD Inc.
5 minute - Two part Epoxy adhesives are really good for the attachment you are wanting to do. O'Rielly's Auto Parts has a good selection and you can read which ones are for metal to metal bonds. Rough up both surfaces w/80 grit (or rougher) and it will stay attached for longer than you will !! You'll have to figure out a way to keep it in place but the five minute epoxy's set up in four minutes 38 seconds......lol I've used these epoxy's on several things on my race cars with excellent results. Keep in mind, Chevrolet has glued the door hinges on their pick up trucks for over 15 yrs now..... Good luck !!
I proposed using jb weld on hamb a few years ago and got severly abused. So I did it anyway. It worked out just fine.
Say what??!? hahaha....I don't think so..... Not tryin to be a **** to ya, bro, but Chevy truck hinges are welded on. That's seam sealer around them that makes 'em look like they're glued on
Yep welded, I used to run the weld ***y area for GM truck cabs, started as a firewall and left as a finished cab, doors werent hung but hinges for front and rear doors were welded on. the roof was glued on to the supports and welded at the edges. Industrial adhesives are very good, dont know how they compare to JB weld, I'd at least get a 3M product. Im working directly with 3M in my current job and there are multiple products for bonding metal to metal with different cure times/ strengths / application. I'd prefer to just weld everything but eliminating weld bleed thru on show surfaces and the resulting metal finishing that can be eliminated give the adhesives the benefit in non stuctural applications that Im looking at.
3m panel bond is what I use for metal to metal bonding.We also use it to install 1/4 panels and door skins at work. Holds very well.Parts would need to be clamped in place until it dried.Down side is its a little pricey,around $40 per tube.
Is there a difference between "Industrial" adhesives that are sold to companies and the stuff you buy from NAPA, Advanced Auto, AutoZone, etc?
Sand off the mill scale from the bare metal, clean the spacer blocks and the firewall with Acetone and use 3/4" 3M double sided tape. In OEM use it holds mouldings, bodyside claddings, Vent Visors...you name it. No muss...no fuss. Ever try to get a "vent visor" off a car in the s****yard or off a door your replacing due to an accident? It's NOT fun.
