Wed Jan 25, 2012 11:23 am

Hey guys, I plan to patch some rust holes on my pan. They are about palm size and I figured to lay down some sheet metal vs stripping the whole thing out. Unfortunalely, welding is not an option so I considered an alternative: 3M 08115 adhesive.

I was sold on the idea and found it locally. It then dawned on me that the applicator is so damn expensive. I believe there is a cheaper applicator gun but it is still around $100. For a paint/body shop i can understand but for the average DIY? Is there a more affordable alternative to this applicator tool or is there no way around it? That is making it a dealer breaker for me. If I had that much money, I might as well buy a simple mig welder.

What? I bought 3M's gun and it was only $40 on Amazon. I think you may be looking at the wrong thing.
I don't know how well it works, but you could always push some of both ends out and mix it together and spread it. It's just an epoxy and activator.

:? Just my .02 but the fine folks at 3M spent loads in r/d on this stuff. From the automix nozzles to the gun. I bought the gun etc...didn't like to but I didn't want to run the risk of a poor mix...do you? I used the adhesive and the seam sealer and so far so good. It sucks but do it right or buy a different product.

you can buy the cartridge , 6 tips and the gun for $105 on amazon. gun alone $54. yes you can push out equal amounts mix well and apply.

Not all auto paint stores are equal, but my local one will buy the gun back if returned clean.

Be careful mixing that adhesive without using the tips. You won't likely see it, but mixing by hand can induce tiny air bubbles into the adhesive, potentially weakening it.

^^thank you!

they make the guns and the tips for a reason...not just to make oney off you.

considering the tips are only 10 bucks for a 50 pk. and a used gun off egay is like 40 too...it's really not hard to invest in peice of mind.

For small patching you can use this adhesive. It comes in tubes and is extremely strong. Ive used it on doorskin bottoms. Try amazon.
All you arguing experts: save it.
