Remember someone somewheres talking about doing this. Seems counterintuitive.
Anyone do it?

Sanding ablative bottom paint
- Thread starter Drinky Crow
- Start date
I do every year. In a typical season some of the ablative wears off, but I do give it a light sanding before putting on a new coat. Manufacturer’s instructions even recommend that. See for example https://www.pettitpaint.com/media/4361/pettit-paint-compatibility-chart-2019.pdf.
Oh I see. I'd used mod epoxy in past, but there's soft and hard ablative.
What do peeps like in teh PNW?

I saw a recommendation from a previous post. someone posted using a Sheetrock sander. I want to try that next year. Usually I simply sand down buildup areas that I can easily get to. With the sheetrock sander it would allow more reach without tweaking my back
Not racing here. Put on Pettit Trinidad 2 years ago. Diver says it is holding up well. Have to pull the boat, when we get permission to install a couple of thru hulls. I'll take photos and let your know.
@LeslieTroyer did his boat in SeaHawk. This was a repaint. Boat was clean when taken from the water (3 years old I think). Yard guys were impressed as they had a "light pressure wash issue". We sanded the boat with 80 grit to give the new paint something to grip too. Basically roughed the surface.

80 is my preference. That’s what Pettit recommends for the paint I use. I do prefer to use the net/screen style sanding disks instead of paper. Seems to clog much less and last much longer. I can sand the whole bottom with 2 or 3 of those disks.
Oh, No, I meant for prep before painting, with a random orbital sander.
If you mean for burnishing after painting, I’ve used 400 wet for burnishing Pettit Vivid. I may have used 600 at some point too, I don’t remember.
