Our catboat is red and it looks right somehow. Our Islander is blue and I am getting tired of it.

Faster's point about having a "flag color" under your finish color is good practice. Remember it is a simple thing to change so don't spend any sailing time deciding. Perhaps next year you will try something else as long as it is compatible.

Re: Bottom Painting and color question

If you have choices for paint locally, but not what you have, you can put "OTHER" paints on what you have. But it must be compatible.

IE "generally speaking" an ablative can go over other brand ablatives. Do not put hard over ablative, but ablative can go over hard.

Many times paint brands have a listing of what that variety can go over, or the store might have a listing of what is compatible.

Re: Bottom Painting and color question

Interlux Ultra is a hard paint. Don't worry about changing colors to get a flag coat, it won't slough off anyway.

I'm surprised that you removed a couple hundred dollars of almost new paint. Its nice for the colors to look good, but even nicer to not spend the money.

This is a wive's tale. Most copper-based anti fouling paints are compatible with one another, regardless of whether they are hard or ablative types. Hard paints can go over ablatives and visa versa. It's all in the preparation.

Actually I dont think I sanded off a lot of paint. There was a heavy wite colored layer of oxidized something. I suppose I could have pressure washed it off but i wanted to make sure I could get it off. So sanding was light. This was originally the question in my mind before I started thinking color change. There is still alot of paint left except for a few spotty areas where it was flaking off the hull and had to be taken down.So I guess I would pick up a pint of something hard and red and just tough up those spots before launch. Maybe add one more coat on leading and water line areas well and let the rest go until a haul out for topside paint probably in a year. Does that sound possible?

Re: Bottom Painting and color question

I think it's pretty unlikely that the paint applied prior to 2005 will be effective at all. You're going to need a fresh coat of something.

That does seem to be the definitive question. Is there still activatable chemical still left in paint that was applied somewhere between 2003 and 2005? Finding no clear answer to that question and being at least open to a color change, I picked up my sander.

Sanding is your future.

Weird that the quote you made of my post is not exactly the same as my post. No harm done, just didn't think I remembered putting it that way.

Thanks for the input. As to your quote, I was typing on cell phone and it has some erratic cursor movement. I think I typed over some of your quote by accident.
