I reco'd my fire extinguisher off the boat.
Its one of them weird things that goes off at 79c and has some whizzbang gas in it, that smells like citrus and is really good for fires around sensitive things like electrics.
Now, the base of the thing and about 3 inches up was going rusty and I was worried about it getting a pinhole leak, so I very very carefully hit it over the crook bits with a very worn flap disc and buffed all the crap, bits of rust, old paint etc. off it.
Treated it twice with corrosion rust convertor, hand sanded it, then put 2 coats of kill rust silver over it followed by 2 coats of bright red.
Looks like new now and I didn't set it off or anything stupid.
Its still full and ready to roll, but a new one was gunna be $1,000 to $1,200 and I've done this one over with crap I already had in the shed and a $4.00 can of red paint.... bargain.
