Bottom paint primer removal?
Can anyone help?
I bought a boat last year that was in salt water and will now be in fresh water. The boat had bottom paint which dried out and we scraped off. However, the primer is still on the bottom; has anyone ever removed primer? What is the easiest method?
Thanks for your help,
Mike

LOTS of work....................................
Sorry to say that most marine primers are "thermoset" polymers which means that solvent will NOT move them so it's not like you can wash it off!
Your best bet is to sand it maticulously with a DA (dual action) sander with a #120-180 grit paper. then move to a finer "finesse" paper. 3M makes a good quality type "Hookit" paper and will leave the hull clean of primer down to the gel. Once you hit the gel, be careful not to go too deep and then start wetsanding with a #400-600 grit paper. This will smooth off the gel and then apply a good wax such as"Leverage"
Your done.
My boat had bottoming paint on it too but was totally removed using these steps outlined. Took about three weeks of hard work by the former owner and I spent a whole day buffing with rubbing compound before applying the Leverage. Mine looks great! Smooth and clean and should slip through the water very easily.
