DING DING DING... We have a winner.
After shopping the $20-$50 foam cannons on Amazon, and reading tons of reviews. I went to YouTube and found the results. Everyone that has made the investment in MTM has not regretted it.
But just like the idiot that spends way too much money on a toy that sucks, they are usually the last one to admit they made a poor choice. I, on the other hand, feel it is a service if I made a financial mistake.
Honestly, the MTM foam cannon, gun and 50ft of commercial grade hose cost more than the pressure washer. But I literally can walk around my entire boat without moving my pressure washer! And I have quick connects from the spigot, to the pressure washer all the way out to the tip of the lance. It just plain works (without leaks)
The 242LS is big enough, that I have to foam it in sections. As I want to let the soap loosen up the dirt, but not dry on. So I do a side at a time, and interior at a time. Rinse, Foam, Hand brush or rotating pressure brush, then rinse again. After that I decide if I need to use buffing compound to remove bumper rash and then wax to be sure all water spots are gone. Finish the white portion of the hull with acid wash and rinse. Condition the tires and all plastics.
I even simple greened my engine bay last night. I should have waited till I did my oil changes, but I can wipe that up.
Good luck!
