The correct tool for the job. Background: come May will get boat out of storage n polish her up (24 ft Cobalt).scale of oxidation from 1-4 is about a 1.5/2 . No electric power to polish so last year (3.5 scale)used a flex xfe-15-150 orbital long throw and a PE-150 rotary ( last year some wet sanding, then wool, then foam, using Marine 31, followed Mike’sMarine 31 book). Is there an advantage of adding the new cordless beast (xce8-125) to the mix since I have the long throw cordless version.
