DIY Soda Blasting

IMHO
don't lift the boat off the trailer... If it's a bunk trailer jack up the boat and place a couple double stacked 8x8 blocks between the bunk (directly over a bracket) and the hull in two places.... blast and then reposition the blocks to blast where they were... then repeat the process on the other side....

If it's a roller trailer then simply blast in place and then roll the boat back to get the spots where the rollers were.

a Tyvek suit and a forced air (from outside) hood are your friends.... The job gets easier when you can just lay in the mess without worrying.

You can make your own air supply with a small blower and a length of flexible hose BUT make sure you put a filter on the intake.... you don't want to have a very pissed off yellow jacket blown into your hood!
