Sand blast and paint trailer

I have a golf cart trailer that has been exposed to severe bad weather. The trailer is badly pitted and rusted. Some pitting on the fenders is almost the size of BB's. (Almost look like barnacles) I want to sand blast and spray paint it. I have a suction blaster, air compressor, etc. Does anyone have suggestions on the size grit, pressure settings, and procedure for best results?

Do you have a siphon fed sand hopper or a presurized tank?

I usually use whatever sand I can get
Sandblasting the whole trailer with a diy type sandblaster is a BIG job. Sandblasting takes a lot of cfm so you are limitted to a small tip. Unless you have plenty of time to clean this up I'd consider having it professionally done - providing it isn't so far gone that rust removal will leave you with little meat left

I agree with Mark that sandblasting more than something fist sized with a small sandblaster is a waste of time.......even if you have a lot of it.
A pressure pot blaster is good but in order to run a big enough nozzle to do the whole job in reasonable time takes more CFM of air than a normal home compressor can deliver.

If the pits in the fenders are as deep as you say you would do well to just take off the old fenders and replacing them.
They are not that expensive.

A wire wheel in an angle grinder will make short work of cleaning up the frame.
