I'm starting to get polish envy.

Been prepping the arm for a mirror polish i hate prepping but if its prepped properly the differance in finish is amazing . These old metmachex arms are made from top quality alloy

How are you prepping ?

I am still learning to polish alu, so any tips are welcome !

[rgstu]

First give what your prepping a good clean i depending on the cond if its pitted i start with 400 grade and work my way up to 800 then use a fine scotchbrite wheel then back on 800 work your way up to about 1500 grade ang then i use the mops using brown up to blue soap and then a fine pink soap with a soft mop be sure to use some fairy liquid in your water with the wet n dry

thanks, will try that.

I start with 400 grid to sand out imperfections, going up 200 grid at a time up to 1600, then a sisal disc, followed by 3 compounds on the buffing wheel.
Result is very nice, just not that chrome-like finish.

You can get wet n dry up to 3000 work your way u to about 2000 plus also it depends on what mops you are using how powerful is your motor ? I use 2hp i like to get tp this stage before using the machine

Rear wheel is almost a straight fit all it needs is the captive spacer needing 5mm off so the caliper hanger fits if i was using a bandit rear caliper but im using a little ap racing caliper and will need a smaller disc and a one off hanger made

A little buff up but no where near finished
