Scratches in ali
matty h - 5/5/11 at 06:59 PM

I have made a trim panel out of 1.5mm ali sheet to go on my bonnet around the air filter that is poking out problem been that I have scratched it any suggestions on how to get rid of them.
Thanks Matty

Sand with progressively finer grits of wet and dry paper and then polish. Starting grit with wet and dry depends on how deep the scratches are. You will probably have to do the whole piece to get an even finish.

Cheers

agreed wet and dry (keep it wet) I use WD 40 to keep the paper lubricated, start with 400 then 800 followed by 1000 and a polish

+1 except use parafin instead of WD40 and go upto 2000g, to get a mirrir finish, mop it with Farecla G3

Cheers guys sound like it needs a good coat of elbow grease.

I use T Cut and fine valve grinding paste applied with an orbital sander,(1/3 sheet type,cost about £10 ) fitted with a soft cloth, instead of the usual sandpaper sheets, for small scratches. That way you can do large areas without so much elbow grease, which is expensive, if you value your time as much as I do.

Or use a brillo pad - far quicker and a lovely patina finish...

Think I will give the different ideas a go on a off cut of ali before I go for it on the trim panel.
