As per Marks comments...Andrew i would just get an 80 grit paddle wheel for your grinder and run along the edges where the welds are, if your using a mig i advise using a gas shielded unit for better quality. then once done you can get the whole lot blasted and she should come up a pearler. i got quoted about £400 to get my tub blasted so opted for steel wire mandrells and grinders.... managed to get my hull back to shiney steel then used an etch primer followed by a few coats of red oxide and first coat of base (light stone)......must add this has only been done on the lower hull away from where i will be putting hot rivets.
have fun
