Bronze props polishing

[Marty87]

Hey guys I’m looking to polish my bronze props and rudders to a mirror finish then wax with lanolin for protection has anyone had experience doing this and if so was there any Prop slip and was there much fouling after a season,

My Boat is a princess 380 with tamd63p 370hp on 4 blade 23.5 x 32

Hi I have a princess same set up, the only thing that works is propspeed but it is very expensive, I tried the new silic one propeller paint from Hempel, it stripped back to the primer after a year so now I just polish them up every year. Nothing much else to say really its just one of those things to add to routine maintenance ! Never had prop slip so far.

My boat has just come out after 14 months just a bit of slime on

So far best of a bad job has been prop off and dipped in brick acid. Hammerite special metals primer and then trilux spray.

To get the best finish you need a metal polishing soap suitable for hard metals and a polishing mop.

It's much easier if you polish with the prop removed, on a fixed pedestal or bench grinder fitted with mops instead of grinding wheels, but if you can't do this you can use a polishing mop on a flexi drive, but it takes longer.
It's quite a lot of work either way but you do get a good mirror finish at the end.

If prop is scaled (hard to remove as scale is so hard) I use one of these

Non-Woven Preparation Wheel 115mm

it is like a solid scourer
nightmare to find on screwfix as described as a non woven preparation wheel so usual common sense searches cant find it

Hi guys thanks for your input up to now I have used a poly disc on angle grinder on my props, rudders, p brackets and started to wet and dry sanding my rudders from 240 building up to 1000 grit so will continue this on the props and p bracket and finishing off with lanolin for protection and hopefully by next season it’s only quick clean up and a little polishing.
