Got off my lazy butt this weekend . . .
Finally found some time to work on the truck a little. I managed to wire-wheel all the scale and gunk off the bottom of the bed and inside of the wheel wells, plus I removed all the crappy bondo work from the wheel wells. Then I ospho'd the entire bottom of the bed.
For anyone interested in this part of it, I used one of those pump-up garden sprayers with the flexible wand sprayer. This let me pretty much saturate the inside of those two enclosed channels with ospho. I'm tickled to death with the result.
Now I just need to figure out how to get a sealant of some kind on the inside surfaces of that channel. Suggestions are totally welcome there. I'll go back and brush up the loose stuff (ospho will eat paint if it sits puddled up overnight). I might hit it with one more light coat of ospho, then dry it out with the blower tip before shooting it with undercoating.
I still need to weld in new steel in the wheel wells and in the gastank corner of the bed but I can do that from the top side.
Anyone know why those tubes run up through the bed in the corner anyway? I'm going to have to cut off that boxed in steel to check things out anyway and will likely replace it with something more easily removeable for maintenance.
Anyway depsite hte staggering amounts of work require yet, I still get a charge and a lot of encouragement everytime I get a little progress made on my truck.
Hope your weekends were as good and safe as mine.

hi martin
I believe brad has a method for sealing that channel, its here somewhere in another thread. The tubes coming through the corner of the bed are for gas tank ventilation, there is a condensation tank attached, under the cover. The cover
on my 74 is bolted on, I don`t know if mazda changed that on the 77?
Sounds like you are making progress on the truck, keep up the good work!

i just sprayed gobs of JASCO paint stripper in the channels under the bed, hosed it out. Sprayed gobs of Metal Ready in there to derust. Then sprayed undercoating in there thru each end. Sprayed and sprayed.

Fr#*!'in rusty cover bolts...
Is it really the 'best' idea to go straight from 'ospho' type treatment to undercoating application, without primer and topcoat first, nevermind the hidden location? Seems your 'spray wand' application method is THE way to go... perhaps finding/making a bit longer, specially tweaked spray wand is in order?

Agreed. After paint strip and Metal Ready deruster I sprayed Rustoleum zinc galvanizing primer and black epoxy paint. That sealed it up real good. Then Undercoating for protection and more sealing.

Probably. THe ospho was necessary, that much was obvious. Now that hte majority of it is dealt with I can reassess next month when I decide what to do to seal it.
You're SUPPOSED to be able to paint right over the ospho, according to the instructions on the bottle, but we'll see what the situation looks like.

Actually the wand on the spayer was about 15" long. It slipped easily (very flexible) into the holes in the channel. That garden sprayer was less than $20- @ your local home improvement megalomart. My only regret is that I can't spary some other sealant with the same applicator.
