Re: Stus-List Painting Flexofold props?
Josh, I have been using the Pettit product for the last three years on my flex-o-fold. The results have been great. I may have 2-3 barnacles on the hub when I haul out. I was diving to scrape several times before. Highly recommend the product.

Re: Stus-List Painting Flexofold props?
Andy, I think you may be confusing propspeed with the Pettit 1792. As I understand it Propspeed results in an ultra slippery surface which simply prevents biofouling from having anything to attach to. A small kit can run $300. The Pettit product is according to the label ~55% zinc while liquid. But once the solvents evaporate it leaves a very high concentration of zinc. A single spray can is ~$30. The Thiox product I mentioned earlier is actually Velox and actually releases a biocide. As such it is quite likely the most hazardous and unfriendly to the environment. It costs ~$100. Of the three propspeed is just too expensive for me to try. Between velox and Pettit, neither seemed particularly better than the other. And if you can find cold galvanizing paint for less than $30 then your idea is probably the best option. https://propspeed.com/ "Propspeed is a foul release coating, not an anti-foul, so it doesn’t harm marine life. The top coat on the Propspeed system is an ultra-slick surface that marine growth can’t grip. Propspeed’s effectiveness does depend on movement of your boat - the more you use it, the better Propspeed performs.

Re: Stus-List Painting Flexofold props?
Propspeed is mostly zinc. The thinking around here is that plain zinc paint will do the job as well for a fraction of the price. I just painted my MaxProp with cold galvanizing paint again. It seems to work as well as anything else I've tried.

Re: Stus-List Painting Flexofold props?
I used to use Pettit 1792 and then followed the max prop guidance to use Thiox. I can't exactly say that the Pettit was better or worse. I was planning to use propspeed this year but the expense is outrageous and it doesn't purport to last more than a year. TBH the only reason I stuck with Thiox so long is because the can just lasts and lasts. As a result, it is probably the most cost effective though it is not the easiest to apply and is very hazardous.

Re: Stus-List Painting Flexofold props?
Last time I had a yard do bottom work they suggested zinc rich spray paint (cold galvanize). I let them apply it and two years later it looks pretty good, no hard growth at all. This time I did my own bottom work and I redid the prop the same way. It’s certainly cheap enough.

Stus-List Painting Flexofold props?
I have used Pettit 1793 on the Maxprop 3 blade folding prop on my last two haul outs. It holds up for about a year or so here in the Pacific Northwest. I suspect 1792 is comparable.

Re: Stus-List Painting Flexofold props?
FWIW, my Flexofold prop is painted with a product used by most of the commercial fishermen in Eastern NC called Propspeed. I don’t know anything about Pettit 1792. But past efforts to use bottom paint on a prop have not been very useful. The bottom paint tends to sluff off pretty quickly, probably due to cavitation.

Re: Stus-List Painting Flexofold props?
Bruce, The last time a yard convinced me to put a coating on the prop was a decade ago. My experience is that a painted prop quickly loses its paint in a short amount of time. The last several times I hauled my boat, the prop was mostly clean except for a barnacle or two - there was far more growth on the bottom. I assume you have a diver who cleans your bottom regularly. The prop is an easy clean. Others may disagree, but I think it’s a waste of money. All the best, Edd ———- Edd M.
