First Time boat owner

[Garyh]

Hi All

I have just bought a 2005 maxum 1800SR it needs a bit of tidying the question I have is
Do I need to remove all the old antifouling from under the boat before applying new.

Thanks
Gary

If it’s flaking off you should remove the old paint, if it’s not flaking you just need to do a light sanding.
