rusty floors

[Z-71 ripper]

hey i just bought a 93 GMC 1500 with Z-71 suspension, 4.3 V-6. i lifted up the rubber floor may and found a little rust then i lifted it up further and saw a bad sight. there was a good size rot spot forming and 3 small pin needle holes so i ran down to the local napa and and picked up this stuff called rust mort. i put some on and i looked to work alright but i would like someone to reply that has some experiance with it and if its actully worth $17 a quart. and can someone answer the question of whether my truck is a 5 speed or a 4 speed? it has a granny gear, 3 regular gears, and an overdrive.

any help is appreciated:damnit:

I POR-15ed my engine block with the kit they sell.

I've used engine rattle-can paint on a couple of blocks, but none of it lasted for more than a month or a couple thousand miles.

This engine smoked a LOT and stunk bad for the first 300 miles or so, now it's like part of the block. I tried to gouge it with a screwdriver and the stuff was like steel. Not a single bit of flaking and I've put about 2,900 miles on the truck and oil and coolant have been seeping on it pretty steady (bad oil pressure sending unit and a leaky upper rad. hose). POR-15 is liquid gold and the engine enamel is fricken awesome too.
