Should I paint my prop?

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?

    Leave them bare, swin down in the summer with a scotch bright pad and give them a little rubbing. If you use a steel brush it will leave deposits and they will rust. A stainless wire wheel on a drill polishes them up nice.

    I’ve always heard that stainless props should never be sanded or wire brushed... I think it causes pitting issues.

    When I got over spray on mine from painting the out drive, did not stay long!

    If you use your boat it will stay clean

    Once I painted mine with Primocon metal primer and Trilux antifouling paint.  It was just leftovers from painting the drives, but I did a careful job of it. 

    I drove the boat 8 miles to haul out for maintenance, and the paint was gone.  That was the first and last time I painted the props.

    I would go without paint and just take an old washcloth or scotch bright (as mentioned) whenever you are in the water.  Definitely better to have bare if possible.  I know in my area that most people do not paint their SS props (we are in brackish water).

    Too late on not using steel wire brush on them, oh well.  Might just try waxing them a few times and putting them in for the season.

    I found out the same way... after I wire brushed the stainless props on my old Maxum! Lol

    I beleive the thought is that the wire brush leaves microscopic scratches with low carbon steel deposits in them which promotes galvanic reaction, therefore pitting etc. Just thinking out loud, but would a quick shot of muriatic acid or some such help remove that? Probably not?

    Willhound I have heard that muriatic acid is not recommended on any metal. That is why I was thinking wax?

    I clean my props every year with muriatic acid,I do remove them first so I don’t get the acid on anything else.

    I just spent hours trying to strip off the prop paint i put on last year.  Don't do it again.  Still haven't gotten it all off.  I honestly don't think that it helped at all vs leaving it bare.

    I use a stiff poly brush that I put on my drill..  it does a great job of cleaning any growth off. I also use toilet bowl cleaner and scotch pads on areas I can't reach with the drill. 
    I have read the only paint that works well is Prop Speed..  it is however insanely expensive....  I would only consider if I was in the water year round

    I will clean my props as well as I can and put them back on bare. I can brush them off from time to time if I see growth. We shall see!

    I clean my props and trim tabs every year with diluted muriatic acid. Then I wash with soap and water. It cleans them up really well.

    Thanks Greg, I will try exactly the same thing.

    Last year was the first time I used this method and they sparkled like never before! When hauled for winter they actually looked cleaner than they had in the past when hauled. Placebo effect maybe but they do look cleaner, once out of the bunker I'll clean them up again before launch.

    You may have something there as prior cleaning of mine had been with brushes etc and so that may explain why this year they do in fact look better after hauling seeing as I used the acid last year.
