Gday mate those soda blasters are a good piece of kit i used mine to clean a lot of the water galleries in the head .head cover and block of calcium on my 40 hp when i had it stripped down even cleaned the carbon of the pistons, the beuety is they do very little if any damage to the work piece and for a very small amount of money i rekon it is well worth it in time and effort . I have the unenviable job of sanding the whole boat top bottom and sides to restore it , the joys of a resto take care.

Won't lose any hair protecting that head with them safety glasses...... joking aside, great job! its a very informative video. Thank you for your time!

Quite surprised it was able to blast off even down to the next layer in spots but does no harm at all to the gelcoat above the waterline??

Will this remove the Gel Coat also?

Have you tried using a pressure washer to remove the Total Strip and paint instead of scrubbing?

i made mine with pro prom pf747 work faster and make nice job
