I redid the bottom of my Shark last spring too! I took of the old soft antifouling paint (not sure what it was but it was reddish). I used a scraper and the palm sander with 80 moving to 180 grit (no other sanders needed - definitely keep the belt sander away!)
I used a layer interlux interprotect before adding the vc17 (mostly because I went through the gel coat in a couple of places), it might have been over kill but after a year in fresh water, the vc17 still looked great!
Maybe you could the Interprotect as a primer over the hard paint on your hull. I also used the Interlux 202 thinner to clean after sanding.
I bough four cans of vc17 put 3 on for the fist 2 coats, and saved the 4th for the haulout this year and it seemed unneccessary.
Good luck to you.

Here is some more information from International. Note that, if you do not remove all other anti-fouling paint, you'll need to use a primer. PrimeKote, if I recall correctly. VC-17 isn't compatible with other anti-fouling paints.
Usually the easiest way to determine if you have a compatibility issue is to take some of the solvent for the paint you wish to apply new and try that solvent on the old coating. If you can rub off paint with the solvent, you're going to have a problem with the new paint. Either strip or prime, with stripping being the most desirable if the most arduous.

Yes you can. Here's the data from Interlux:

Can I put VC-17 over hard bottom paint?
I am entirely redoing a shark 24 and want to put VC-17 on the hull. I have sanded off the yucky black antifoulign paint and have gotten down to a hard paint layer(s). I am not sure if I can apply VC-17 directly on to this. The paint is a copper/gold color, and some areas where I have sanded through this copper/gold layer there is a coat of a hard blue paint showing through. I have no idea what brand of paint this is, but can I chance painting VC-17 right on this? Any other ideas for a really fast bottom paint for freshwater that does not require me to sand right down to the hull. I am not even sure if I could sand down this hard paint, it is EXTREMELY difficult to sand away. Worse case, is there a primer I could put on between the existing paint and the VC-17?
Also, any other really fast bottom paint alternatives worth looking at? Any new Teflon paints out there anyone is aware of?
