Anyone know of a good paint that will stick to an Aluminium prop??? I have tried several different cheap brands of paint like Krylon and the paint comes off after using the prop at high speeds...

Forget about it! Why paint a prop? And if you did manage to find some that stays on (maybe epoxy paint) after intense sanding,you better make sure you don't disturb it's fine balance or you might have to pay for a hefty lower unit repair.

I have to agree with Jay, but if you're really serious about it look for a plating
shop that does hard anodize, we use it for
added durability on aluminum tooling. It'll
give surface hardness of about 60 rc (equal to tool steels), not too expensive and looks
great, comes in colors.

POWDER COAT WILL STICK.

FLUKEDUKE: Great idea if you must coat the prop,.0005 to .0015 thick should do the trick. However,the prop must be cleaned properly.A good shop can do this as part of the plating process. whalersman: Call a few machine shops in your area and I'm sure they will direct you to a good plater in your area.

"Hard Anodizing" will not turn out well on castings, only forgings

Running the prop in sand takes the paint off rather quickly. So does cavitation.

I had this particular prop reconditioned by a local prop shop. After using it for the first time some paint started flaking off.
New aluminium props come painted from the manufacturer.
My question is, What kind of paint does the manufacturer use on their props??
