Inside for rust removal?? I always have. Small sand and lightly. It doesn't take very much with a quart sized hand-held blaster.

Power wash the tank out with hot soapy water and you'll be fine. Small grain sand to sand blast or sand it. Whatever you want.

Can't answer that question, but my input to this is, yes I have sand blasted in the past, and the only place that I have ever found it, even with a hood on was in my ears! lol. Not sure why, sorry to hi-jack the post, but true!

Unless severally pitted I would just hand sand. Sand blasting is hard on tin work if not done correctly.

I've done it both ways. I have also got a gas tank leaking by sandblasting.
I prefer to sand, first with a pretty aggressive grit sand paper, then neutralize the rust, fill all the rust pits and start sanding again.

Get one of those rust/paint stripper wheels for your grinder. They do a terrific job of cleaning off old paint and rust right down to shiny metal. Smaller ones are also available to fit in your drill for tighter places. I use them all the time in my shop.

Whenever I had sandblasting done, I have the frame rails, torque tubes, and bascally anything on the drivetrain blasted. When it comes to the sheetmetal (and fuel tank) I use an aircraft stripper to remove the paint. I then wash it down good to get the excess stripper off. For some tough spots I may blob a little more stripper on the pieces and use medium steel wool to loosen and get those tough spots off, wash it down again, and shoot some primer on the pieces to keep from flash rusting. Sandblasting sheet metal can make the pieces lumpy and do more damage to the sheetmetal. Small pieces like linkages, levers, tool boxes I'll low pressure glassbead. Those parts come out nice!

I have sandblasted 4 tractors including sheet metal. Never had an issue other than a ton of hard nasty work. Even with ear plugs, full respirator, full paper suit and a hood, sand always found its way in every crease. Does a great job of getting the paint off but man its dirty work. If there was someone close that soda blasts that’s the way I would go. You do need to be more careful on thinner metal or you will eat a hole through it. The sanding pads work well on the cast that the sand has a hard time cutting the paint since it is not smooth. You do need to be careful with the sanding pads as they will scratch the metal if used to hard.

If I had a gas tank leak after sandblasting (small sand/handheld small blaster) I would consider myself LUCKY !! Better to find a flaw before the expensive paint job getting ruined months later.

I was using a full size (siphon) sandblaster. The tank was very rusty (inside and out). I ended up cleaning and sealing the inside, but in hindsight, I should have found a different tank. By the time I got done, I had a lot of time and money in tank that looks good, but is very thin. It had held with no leaks for about 5 years.

That's why I take stuff to get sandblasted to my sandblaster just to avoid the mess! I'm fortunate that I have a personal friend of mine that's only about 45 minutes away that has a sandblasting shop. I have him shoot a filler primer on them when he's done. Save's me a ton of work n' mess and is worth the dough in my case! Steve@B&B

Is there a kit you can add to a power washer out there? Seems that would work good,I'm getting ready to do a d21 and that's some heavy sheet metal, but still gonna be careful with it

I have one of those pressure washer/sandblaster kits (from Northern Tool). I am not impressed with it. It works well at first, then it will not suck the sand up the tube. Somehow, the sand always seem to end up wet and then it is junk.
I have much better luck with my siphon type blaster, but it takes a lot of air. I blast for a while, then I have to wait for the compressor to catch up.
