About to repaint exterior sun visor & the aluminium strip has some imperfections as aging ally does, that need to be 'sanded' out,
has anyone tried this & how did ya go about it

Nic,

You could get some real fine wet and dry and take the scratches out of it, followed by some cutting compound and a motorised buff, and then finish off with an alloy polish.

I used the buff/compound/polish method on mine and it came up like new, although it does discolour/oxidize and needs re-doing regularly.

Cheers,

Craig.

Craig would  something like 800-1200 grit paper do the job

Nic.
i dont really know much about the piece you are talking about but if this piece is alloy, then i would start out using say 800 (depending on how bad the marks are) then work your way up to 1200-1400. i would be using autosol right the way through doing this, as it will get the shine up. after that, a finishing polish should make it all nice and shiny, and the shine should stay a quite a bit longer...

cheers

A coat of clear, either rattle-can, powder coat or that POR15 gear will keep it like new, just give a quick wipe over when it gets dirty.

Nic,

I was thinking more like 2000 wet and dry, I reckon 800 grit is way to coarse for this purpose, but what grade you start with will depend upon the type and depth of the scratches.

Autosol is perfect for finishing off, or I use the Mothers Aluminium polish and find the results extremely good.

Cheers,

Craig.

Darcy its the aluminium strip across the front of the visor & would ya sand,autosole,sand,autosole etc, etc
Just dont want to stuff it up as I only have one & they're not a dime a dozen to replace

dont use 800 grit u will do more  damage than you started with 2000 grit and slowly but carefully it will tidy up then a chrome polish and clearcoat  and it will be good for years to come

[Papa Smurf]

Craig/Darcy its not so much scratches as bubbles (for the want of a better word) that aluminium goes like when left to the weather & gets older with time

[Glenn 'Stinky' Stankevicius]

Nic, are the bubbles hollow or can you sand them down?
If they are hollow, you could sand them off then fill the holes with bit of bog and paint it silver.
If they sand down to a flat surface, follow the directions for polishing above.

[Papa Smurf]

Stinky they are bumps & I guess impurities in the ally, which should/will be able to sand down.
Its not tooooooo bad just annoying to me.

when i polish alloy, i get a little piece of sandpaper, put a little polish on the paper and start polishing!!

although, after i think the piece is up to scratch i use  finishing polish, i usually use purple polish, which is quite expenisive but does a great job.

[fccool59]

is that stuff called purple stuff from autosmart or is it the stuff from the usa or am i thinking of the wrong stuff?
