Any of you guys ever done a "partial job" on bottom paint? Regrets?

If you have a good rapor with a local hardware store, take it by n ask them to shake it for you. Worked well for me.
 
I did the same thing on Saturday. 2 weeks ago I found the paint from last year and flipped the can over. Then last week I flipped it over again. The cool thing about this trick and planning ahead is that it doesn't absolutely freaking nothing. When I opened up the can I had black water sitting on top of black cement.

I think I spent more time stirring than I did painting.

I use a paint mixer drill attachment to stir mine. The problem I have though is "lumps". Thick paint just does not seem to last very well in a can that has been opened and used down below about 1/2 can.

Oh yeah, and re the original question, yes. I touch up every spring before launch. I do the visible and high wear areas, and then the underside where it needs it, or until I run out of energy or interest. But that is fresh water so we don't get hard growth.
 
Did you tape it, or just free hand it?
I typically just free hand it. But that part, of course, is completely up to you and how you want to do it. With one finger on the boat as a steady guide, it's not that hard once you get used to it.
 
I taped mine and then used a 4" roller to apply the paint. Went' quite well.

Here is what you DON'T want to do. A couple years ago I got to the boat to paint and realized I had forgotten to bring painters masking tape. No worries, I had a large roll of cheap duct tape on the boat. So is used that. came back the net day to peel it off, and a LOT of the glue on the tape stayed firmly attached to the hull when I peeled it off. So much so that I had to use solvent to get it off, and even that was hard in spots. So much for saving a few minutes to run to the store to buy masking tape.

This is very much something I would do...ohh man :):)
 
In touching up spots which are bare is there anyting that needs to be done as a barrier coat? Some spots are chipped to the point you can see what looks like gelcoat. Also do you sand to feather out the chipped spots? Aesthetically i think I should on the area visible at the waterline but not so much on the bottom?

I touched up a few spots below the water line where the slings had rubbed a bit of bottom paint off. I didn't prep those areas, just painted on over...
 
Irie, just use a scotchpad and roughen the gel and the surrounding AF paint up a bit. No, you don't need a barrier coat as there was not one there to start with. Your boat is plenty new enough (better gel formulation) that a barrier coat isn't needed.

Good to know, thanks!
 
So I am an avid boat washer so my paint at the water line always gets thin. I use good quality 3M tape mask my white gel coat and do the touch up with a 4 inch roller
