Vinyl bottom paint experts needed
 
Got a new to me boat last spring and it was already in the water, so bottom paint was on. Surveyor says it is vinyl - I have no experience with this type of paint. Can it be burnished and used for the coming season on the Great Lakes, which do not get any warmer than 70 F, and that for only a month.

Eventually, I will be stripping the bottom to gel coat, but not this coming year.

My old Irwin 32 had VC17 which does not build up over each seasons use, which means a quick bottom wash with thinner and a new thin coat and your set.

With vinyl, do most owners take it down to bare every year? If no, how much does one let this paint build up before it is time to strip it down?

I see Interlux is the only vinyl West offers. Any other suggestions for me?

It's been 15 years since I used a vinyl paint. Here is what I remember:
1) Cannot put vinyl over any other paint (See 2) below)
2) It uses very agressive (and special) solvents - beware your hands.
3) It definitely builds up. I let it build until I had adhesion problems then had a major sanding job. Sanding is the only way (other than sand-blasting) I remember to get it off.
4) It did not do a very good job on anti-fouling (I live on the NE Atlantic coast)
5) Only advantage is that it was a very hard racing finish.

I think most hard finishes these days are the modified epoxy type.

Apples and oranges, I know, but here in the Bay Area, vinyl paints have pretty much gone the way of the dinosaur. In saltwater environments they exhibit poor anti fouling properties and have a useful lifespan MUCH shorter than either traditional ablative or epoxy paints. In my experience, anyway. Maybe in fresh water you will see better results. I'd switch to something at the first opportunity, were it me however.
