I agree with garage dog 65....YOU MUST DEGREASE THE FRAME FIRST.Im set up to do alot of blasting at my house, Big compresser /pressurepot blaster but it doesnt mean nothing if you dont degrease the frame first. sandblasting is the way to go but it will not remove grease and becomes more of a mess..borrow a pressure washer and clean it very well, may even get some engine degreaser in a can (its cheap) and soak it the night or two before then....pressure wash away...or go to a self spray wash car wash( i ve done this) and they have great pressure AND YOU DONT HAVE A Grease MESS TO CLEAN UP AT YOUR HOUSE
. throw in some coins and clean it..
I usually buy my sand from Home Depot.Its called (natural play sand)clear bag... reason is.. it doesnt have to be strained and its consistant.WORKS GREAT) .Get yourself a painters zip-up suite (15-20 dollars) usually from the autopaint supply store..I like blasting in these BECAUSE it covers you from head to ankle and its light weight ,easy to move around in.Ear plugs.. even having a hood sand gets in every orfice it can.. Im maybe tell in you what you already know ..if you have any questions pm me ...Ive done alot of blasting.
