I also tore out my floor liner today...got some rust there, it's not all the way through though...took some pics...think I should put that in a new topic?

heck, this one seems like a build thread already, certainly getting enough views... I'd just leave it here...
so, what approach do YOU think you should take?

Glad you asked
I used my wire brush on the angle grinder and got flakes and dust off...but that was it...then I got the 7" grinder with 36 grit....the disk gave up...it wouldn't cut that...
sooooooo....the only thing left is the dreadful sandblaster....or replace the floor pans...or perhaps this is the perfect location for some of that POR-15 stuff...
your learning young shark hunter....
if I was gonna go for a treatment as opposed to blasting, I'd probably get it as clean as possible and use a converter.... definitely start poking around with a screwdriver and make sure it's relatively solid..
This place is hard to get to...sandblaster may be the only way:
the infamous GM trough..... usually where all the trouble starts... great engineering on that one...
Does it serve a purpose? You could fill it in or if you cut out the floor pans there would be no need....right?
it's purpose is to allow a place for the door weatherstripping to fit.. it needs that lip for attachment...
I am not looking forward to the sandblasting....with the rail it was able to bounce off and go into the air...with this location it is going to bounce back right onto me....
in this pic, you can see how i eliminated mine with the custom floor/slider gig... I'll use a straight piece across the bottom of the door to make up for removing the stock section....

well, that's one reason blasting is nice in the winter.. long sleeves, etc...
hope you've got a different helmet/shield than that one that came with the blaster, it's pretty useless... I've actually got some blasting to do myself in the not-too-distant future..
piece of advice... if you decide to blast the area, you'd be wise to trim up/readjust your dash covering and TAPE it along the bottom, at the bottom of the firewall with duct tape... nothing more annoying than sand coming out of your dash a year later. as you've learned, it will go everywhere...
Nice
...you must have a great shop full of tools...when I take the Blazer to the body shop yesterday I was in awe...their shop wasn't as nice as the one on PowerBlock but they had almost all of the same tools...Having the proper tools makes all the difference...if I had a plasma cutter and welder, I believe I would replace those floor pans with replacements...
they had all kinds of sheet metal and benders and all kinds of stuff...
the dungeon.... guessing you don't read my build novel...
I'm fairly well equipped.... good welder, bender, plasma, chopsaw, hyd press, drill press, etc... a lathe a need to get running... items I need, horizontal bandsaw, blast cabinet, yada, yada..

I've been so absorbed that I haven't seen it yet...I need to catch up on what you have been / are up to besides helping me.
And there she is! The "Quint"-cy"
welder....bender.....plasma....chopsaw...hydraulic press...what are you...some kind of half-arsed astronaut?
kids today....they bring along electric tooth brushes....yeah that's some mighty fine equipment you got there Mr. Hooper...don't know what tha bastard shark might do with it.....saw one eat a rockin' chair once.....
hehe, nice... 
I brought out the sandblaster today...I think it was 93 degrees here today...anyway...my sandblaster won't cut it...it hit a spot here and there but on the grainier stuff it wasn't doing anything...humidity was horrible...lots of water in line...
I have tried everything that I own and I cannot get it all out.
I did do the screwdriver test...I leaned on a big philips head with all my body weight on all different places...It didn't go through...there are a couple of pinholes I exposed with a wire brush...I even put the tip of the screwdriver in the hole and it held up....
I've only got two options...take it the body shop and have them put new metal in...or give POR-15 a try...maybe with some epoxy putty and/or fiber mat to strengthen it...
How quickly will it rust out after POR-15 is applied?
By the way...while I had all that stuff out...and was filthy...I took the rear bumper and tailgate off...I decided to sandblast the tailgate cover at least I feel like I got something done....guess what primer that is? Can I paint on top of Ryoken Green self etching primer? or do I need to put regular primer on that?

When you put the sandblasting hood on did you remember to say:
"that's some bad hat, Harry"??
When I was first trying to get dialed in on my sandblasting I was using way too much sand. The correct balance for a home-gamer setup is maybe 5% sand and 95% air. If you don't really damper-down the sand valve, you won't get the speed required to really "cut" on the part. Try a few settings to see what mix works best with your compressor. Obviously, with a small compressor you will run out of air quickly...so watch your pressure gauge and when it gets low just stop blasting and wait for it to build pressure again. Otherwise you are just wasting material.
Moisture is definitely a problem... Compressing air will cause a lot of heat and you'll get condensation as a result. The good thing is that if you minimize the sand mixture you will get less clogging in the nozzle.
Also, use the smallest ceramic nozzle that will allow sand to pass through it. That will keep the velocity up as well... Change them regularly too. Once the ceramic starts to wear out it the orifice gets larger and will waste a lot of air and kill the speed and cutting power of the sand.
Just a few tips that worked for me.
