Back mounted stuff.

Metal foam thrower, like the GLOO gun from Prey. You can do something similar with a flamethrower, using a nitro precursor to make heat produce the final reagent for the foam, but it's clunky and might not work with the new fluids mechanic. Just a back-mounted tank + a flamer-sized 'gun' that shoots out small metal foam 'explosions' to patch hull breaches and stuff.

I suggested a "glob" mode for the flamethrower and the concensus seemed to be that it should be part of a seperate chem thrower. So something that throws projectiles with reagents drawn from two tanks, deposits and mixes them at the desired point.
