In the process of getting quotes to have my M10 trailer sandblasted...so far they range from $450-$950 for the entire trailer. Most of the places around San Diego do a lot of US Gov’t work (Navy) and couple the jobs with powder coating, so I’m small fry to them which may be why some of the quotes are on the high end.
For comparison, the tub itself is ~5’x5’, with the whole trailer (tub, frame, axle, etc) ~170 sqft.
