I'm primarily looking to treat small hardware as in this video - and soften the Ziebart on the bottom of my car so I can scrape it off easier. I may use it to loosen rusty nuts and bolts but I usually use a big impact wrench for that, so it's not a "must." This Bernzomatic with a hose would be great for working under a car, but some of the reviews say it falls apart after a couple years. It appears like a lot of the cheaper units have that problem. On the higher end of things, there's the McMaster-Carr 78155A31 and 78245A26. The 78245A26 puts out half the heat of the 78155A31. The 78245A26 can be equipped with the 78615A15 hose. I don't know if the 78155A31 torch can use the hose. What do you think?
