        It will still take a very very long time if it has and thick rust on it. I have a similar blaster with a 14 hp gas Ingersoll-rand air compressor and it's pitiful how long it take to blast most things.

          Likely only cost you 30-40 bucks to have it blasted. I can blast it with mine pressure pot blaster with my big air compressor in about 15 minutes.

              hi, what was the tank used for , how thick the walls, odd shapes and brackets on it, how deep the rust, is it coated with a thick soft rubberized paint how much does it weight?

              80$/hr for high performing equipment is a bargain, as it removes paint faster than you could apply it.

              And do not forget the mess you will have to clean after...

                If you can take it to them so they can actually see it, they may be able to give you a better estimate on how long it will take. Getting it done by someone with the industrial equipment may be cheaper on you in the long run than trying to rent equipment and do it yourself. If you can remove some of the heavier crud from it first it may help reduce the time the blaster has to work on it too. What are you going to use this for anyway?

                    I've started building smokers and was about to invest in a blaster. I've been getting them done and they've been running $50-75 each time. I'd like to do it myself if I can for a reasonable price. I was looking at this one:

                    I'd be blasting 24" and 30" pipe in lengths of 4'-10' depending on the pit. Is this going to take forever? Can someone recommend a better one?

                    Is this one any better?

                      sand blast

                      A tank that size with professional grade equipment. Going with a commercial sand blast job. Not a white iron job should not take them more than an hour to hour in a half. Regardless of paint and rust. They will have multiple blast tips and a very coarse sand available to get the job done.

                        Just throw it in the back of the truck and haul it to them, no problem. How did you get it home? Since it is going to be a smoker, you could just cut out the door the way it's going to be and build a HOT hardwood fire in it all over.Try to get it almost cherry red. That will make any rust and old paint turn loose, and after it cools you can finish cleaning it with a wire brush cup on a grinder(preferably a 7" or larger grinder). Is this an old propane tank or one that may have had something potentially flammable in it at one time? If so, there are certain precautions that will need to be observed before cutting into it.

                          sorry, it will take forever and will wear out your compressor. blasting with a 5hp compressor is good only for small jobs once in a while. take a look at the equipment where you were going before and i bet they have 50 + hp screw type compressor.
