OT Caulk gun recommendations?

[wierdscience]

I have a few projects where I will be using 3M 5200 and NP1 marine sealant and a garden variety caulk gun just won't cut it. They don't offer enough force to get the tubes moving without bending the handle or warping out of shape.

Any recommendations for a manual cauk gun that hold up?

I have a couple of good ones that I think came from Grainger about 20 years ago. The main things to look for is that it has supports on both sides of the tube so that the tube doesn't push sideways. Also I like the ones that have a built in snips for cutting off the end of the tube and a swing away pin for piercing the seal in the tube.

Zero personal experience but 3M recommends their own gun: https://www.3m.com/3M/en_US/p/d/b40069344/

This one claims a 26:1 force ratio and it's a lot cheaper than the 3M. https://www.amazon.com/Red-Devil-398..._t1_B001CGR6CG

Yes, the piercing pin is a nice feature, don't think I have ever seen one with the cutter, but that would be a nice feature to have.

Thanks, that one is definitely in the running.

I've used this one professionally for 20+ yrs and they are very good. Available at Lowes and Home Depot as well.

Cox is one of the brands that McMaster carries. I'll have to double check tomorrow which one I ended up with, but I bought a 26:1 gun from McMaster for some two-part epoxy that came in a single cartridge and had to be forced through a mixing nozzle on its way out. Really stiff stuff, no way it was going to be pumped by an ordinary gun.

I was happy with the one I got from McMaster but it didn't have a piercing pin or cutter, which was sort of annoying. All of my other guns have both features and I got spoiled. Also, I don't think the barrel rotates... another feature I took for granted.

I would stay away from the Dafeike. I've used one before and while it looks similar to the Cox it just didn't work as well. The one I showed in my previous post is a Cox
