If ablative paint is still on the hull for the most part can I just touch it up? I don't see the need to paint the entire bottom.
 
Correct.
I once did a signal coat of orange and then a coat of black and just touched up where i saw orange.
 
Will you haul and touch up newly exposed spots every month or so?

If there are a number of areas exposed now, the rest may be pretty thin and short-lived since the paint is designed to wear away and expose the new anti-fouling ingredients if there are any left to expose.

But if the only thin or exposed spots are from groundings , debris contact or similar events unrelated to normal ablative sloughing, just touching up may well be reasonable.
 
I use ablative paint and do a full paint about every three years or so. I am on the Hudson River so where you boat may be a factor. I usually do the water line for aesthetic reasons and any bare spots. Too much paint is not necessary and just causes build up. If at the end of the year you see a lot of barnacles, that usually is an indication that it may be time for a complete paint job.
 
Need to know if the ablative paint that's already there is multi or single season. If it's single season, just the presence of paint doesn't mean it still has antifouling properties remaining. The copper leaches out of single season paints when on the hard.
 
The Petit guy at the boat show said just touch it up.

Also recommended as CurrentSea above to switch colors every time you do a full hull repaint so you can easily spot where to touch up last time.
 
Pettit Ultima SSA (Single Season Ablative) is just one of the several ablative bottom paint meant for only one season.
 
I guess if you are using the boat heavily and repaint every year.........
 
Yes, I have been touching up where I have either wore it out by grounding a bit or where it chips off from buildup. Since I am touching up I generally roll wide swaths so I'm covering most of the bottom anyways, and then I also do the sides the usual way for aesthetic reasons.
 
Still don't know if you have multi or single season paint on the boat.
 
I do have the multi season paint, probably 2 coats over the single season.
 
Problem is, you don't know how far down you have ablated. If you're down to the single season layer, then, no, you don't have any anti-fouling protection.
 
I should be ok, I noted that when I attempt to cover the bald spots I pretty much cover much of the other areas anyways, so I think I should be ok as I don't think I have to worry about missing small swaths of hull. Its to physically taxing to worry about covering every inch of hull.
