My 270 has a Volvo DP with formerly painted stainless steel props. They had been painted with Petit Hydrocote a few times and who knows what before that, and they were not that smooth or clean. I pulled them today and sanded, wire brushed and used paint remover to get them down to bare metal. I’d love to leave them bare metal but I wonder if that’s a good idea. We are in salt water for 5 months a year in Rhode Island. What would you treat them with, if anything?
