Yes, and they are pretty easy but as others have noted it's not a very
good way to strip a whole paint job off. Use blasting for rust spots, if
you have a big compressor (4hp or more) you can buy a pressurized tank
blaster from harbor freight for around 75 to 150 bucks that will do just
fine for spots.

Use an orbital or palm sander for scuffing the old paint, it's easy
enough and striping all the old paint off is a bad idea anyway (think of
the old paint as multiple layer rust protection. Should the new paint
get scratched you'll have something under it besides bare metal.

Also old original paint is usually going to be harder than just about
any paint you can apply.

For that carpet glue, get yourself a gallon of xylol, wipe a spot...
wait a few seconds and hit the same area again. Then get to scrapping.
It should come off pretty easy with a nice sharpened putty knife. Xylol
melts the crap out of carpet glue. It'll take a while but sand blasting
wont do s**t to it. This applies on the underside too... built up grease
old undercoating etc. is going to have to be removed with chemicals or
elbow grease, or some combination of both. I would degrease the
underside with engine degreaser, and then scrape heavy stuff, and
finally sand.

And for all of this, get yourself a good respirator rated for chemicals
xylol is potent stuff, and sand silicosis can be lethal.

 

Your job inside the tank was soooo dangerous, I hope you haven't
paid with your life.

So you're lungs are still filled with silica. I imagine the "Black
Beauty", obsidian: volcanic glass will look pretty in your X-rays. Good
luck, man, I'll be praying for you.
