What is the best and easiest way to get bottom paint that is several layers thick off for a fresh coat.

You could sand it but there is usually copper in the paint so you have to have protection and it is a lot of messy work
I have also heard of blasting the paint off with various materials just like sand blasting but not as abrasive so it does not harm the gelcoat. I dont have bottom paint and use a product called On Off Hull cleaner. It is basically an acid that works great but does not harm the gelcoat. I wonder how effective it would be on the paint. I just roll it on the hull with a paint roler and the grime drips right off. It might be worth a try :unsure:

sandblasting with walnut chips is the quickest, easiest and safest and will NOT affect the gel-coat on the hull

Why is there never enough time to do it right the first time, but always enough to do it right the second time.

Over here bottom paint is used a lot. My boat gets every season a new layer done by a professional here at the Marina.

Sandblasting with wallnut chips I have never heard of so I am very curious how that is done.

Using bottom paint one first should chose for the right type of paint there is a kind for motorboats and a kind for sailing boats.
Just sanding is done over here with a boat that has already paint. I would let it do by a pro to get back to were the thickness should be. Next year you can do it by your self and that will prevent layers to built up quick! I, every time when it's done, I like the view of the boat looks to be a real ship again! :wink:

Here you go Roel, you may find this video interesting. It shows how the walnut shells work.
