Thinner for bottom paint

[nipper]

I have bottom paint on my 1991 V20 cuddy (from the days when it spent its like on the ocean). It is now trailered, so I really do not need bottom paint. However, I do not want to go the time and trouble of stripping it, at least not this season. I have some old West Marine Copolymer ablative bottom paint which needs to be thinned a bit that I would like to you use to touch up some areas. Can I used regular old paint thinner or do I need to buy the expensive $15-$20 thinner from West Marine?

I'm surprised it's not on the can.
Read the cleanup instructions. Usually whatever the cleanup liquid is will work for a reducer.
Only problem is knowing how the thinner works.
Mineral Spirits may stay wet for a while and Acetone might dry quickly and blush.

It is on the can, but it says use West Marine Paint Thinner 32951 which is really expensive vs. paint thinner from the hardware store.

I will recommend you use the paint recommended thinner only. Thinners are engineered to match the paint its recommended for.
You MUST trust science on this one :)

I have kept my boats in the water for 34 years....for 34 years I have used regular mieral spirits paint thinner to thin bottom paint(all diff. brands) with ZERO issues. My vote- cheap paint thinner
