caustic on ali will make it look like its contracted leprosy!!
i used it in the base of a burnt ali pan at work and its now only good for emptying dirty fryers into! don't put the stuff anywhere near a frame just in case.
I've been attacking my frame today with Wet & Dry and Brasso... only a quick try but quite pleased with the results... 240/400/600 Grit, then Brasso wadding. There's some quite fiddly bits though, so I was hoping I'd be able to use Nitromoors on those bits, and round the welds.
OK
So the paper i had was 1200
works nicely
but, its still leaving small scratches (as it would)
how to get rid of this
if i autosol it a few more times?
also, when to stop using that bit of sandpaper? when it falls apart?
1500's or 2000's followed by a good hand polish with megs NXT or similar will do you proud ;-)
When going for a true mirror finish cleanliness is important - wash off well and use a fresh cloth for every stage of polishing, a dirty cloth with bits of 800 grit in it won't do well for buffing off the final polish :-(
During the process of trial polishing my frame (After the 600 grit) The finish was a sort of a satin look from a distance which I really liked but, of course, up close it was lots of scratches... is there any way of getting a satin finish, other than anodised?
