Any lasting proven method of painting a prop ??

[crazy charlie]

Only looking for someone that has repainted a prop and paint stayed on prop after using .I have tried several methods ,primers and paints ,prepwork and always get the same results.Paint loss immediately without prop hitting bottom/sand .Part of my issue is that my props are submerged for 5 months at a time.Again ,I am looking for someone that has done this with success.We all have opinions on painting ,priming and prepwork and I have tried most opinions with no real success so looking for a proven method if there is such a thing.Thanks Charlie

If it is that important buy a stainless prop, no paint will stick because of cavitation.

You are slamming the door on “opinions” but I’m going to give one anyway.

Have you tried powdercoating? Gotta change the adhesion method if manually brushing or spraying paint on isn’t working.

Just a humble suggestion. Good luck!

oh yes btw im talking about aluminum prop.Charlie

Sure, sand the prop, wipe with turpentine, immediately apply etching spray primer (available in rustolium rattle can) and gloss black spray paint. Now don't hit bottom and the paint will stay on.

I've always had the need for anti fouling paint due to the water conditions here so 2 coats of brushed on Trilux lasts the whole season. Your waters are probably similar to mine Charlie.

Use the boat more, and you will not need AF paint on the prop.

take aluminum prop and have it hard anodized and no paint required, or clear anodized (best aluminum primer there is), then take the anodized prop and go over with a good etching primer and catalyzed paint. havent done props because I have always smacked them into something down here. however some aluminum brackets have been anodized then painted and appear to hold up well.

OMC used to sell SST stainless props that were teflon coated.

Why would you want to paint an aluminum or SS prop?

 

[Lou C]

In Charlie's boating environment (similar to mine) painting with antifouling is pretty much a necessity because you will get growth on the props even if you use the boat often, depending on location. It varies a lot but fouling can be pretty bad here.

from a friend of mine that lived years on the hook.....

going with the current and having barnacle growth on the prop is not a problem...... its turning around to find your prop is too fouled to go against the current when you suddenly find god.

 

[Chris1956]

Gee, I had my Mercruiser in the NaCl for a decade. The prop never had a buildup I never used A-F paint on the prop. Barnacles would build up, a bit, when I didn't use it. There were a couple of barnacles in the "corner" of the blades, at the end of the year. I did not think they were too important.

Of course NJ is different than the Bahamas. Warm water makes the growth more.

You beat me to it..
My thoughts exactly.
Kinda glad I didn't have to list it as opinions weren't so welcome.

And for what its worth, any paint "YOU" put on probably won't fair well.
maybe a good epoxy paint, but I wouldn't start to tell you how to do it and waste my time.

I had my prop repaired on the FourWinns by a prop shop. They touched up the paint where their repair work was done. First time out it was gone.

In all seriousness, only the fish will see that paint is worn off your prop and they really couldn't care, I wouldn't worry about it.

85% of my boating is on Canadian Shield lakes with rocky bottoms and rocky surprises everywhere. Most years I have to have one or both of my props fixed. He always paints them but I would prefer that he wouldn't. The paint rarely last long so it's just one more pollutant in the water.

I trailer my boat 500 miles round trip all summer long. I couldn't care less that it looks like a zebra, with black and white (aluminum) stripes.

 

[Chris1956]

Gee, with rattle can primer and rattle can paint (plus sanding) the paint stayed on...at least until I hit bottom.

Ok thanks guys for trying.I guess there is no actual proven method that works.Nothing like a new prop!! Charlie

The is an proven but expensive method….Sherwin Williams Polane T polyurethane enamel.

Used it for years to paint industrial equipment. Follow the application directions and let the paint cure for several weeks before using. You can hit it with a hammer and it will not chip.

Problem being..you can buy two props for the cost of a gallon of ready to shoot paint
