Default Polishing aluminium

Hiya,

I'm thinking about polishing my T1FK05, all the aluminium parts like the bulkheads, etc... is this a good idea? And how would I go about doing it? Just stick on the polishing wheel onto my Dremel (the white soft one), apply some polishing compound and off I go? I am most concerned with the aluminium rusting...

TIA

Aluminum doesn't rust but it will tarnish over time.

I've polished a lot of aluminum and it is amazing how good it looks when done, but it will tarnish over say a year or so.

The X-Ray bulkheads may be treated with a coating or be anodised. When you polish you will be taking off either which will affect it overall.

Oops. I bought a used 05 which had a scratched motor mount. I polisihed it with Simichrome; looks good. But did not know they had a coating on them.

DoS, get some "Jeweler's rouge" and use the white fiber wheel on the dremel. Since you most likely don't have to fix any pitting or anything like that, use the green rouge. Run your dremel on the lowest speed when you're polishing the parts. Spin the dremel up and hold it to the stick of rouge to load up the wheel a little, then just take your time and go over your parts in a circular motion for the best results. Since you're already starting with a smooth surface, you should be able to get them looking like chrome. If you have access to a vice, I'd use it. You don't want to launch the part you're polishing into your eyeball at 100 mph. That would be bad. Just put some rubber pads on the jaws so as not to mar the surface.

Brasso also works wonders ... my FK05 bulkheads were tarnished and this brought them up nice and shiny again

if the parts have scracthes in them use wet/dry 220 paper(or finer) to sand them out, then polish with jewlers rouge compound. i use a bench grinder with a soft polishing wheel on it. i make large scale car models and use aluminum for engine parts, exhast, rims, basicaly any and everything. parts come out smooth as glass, and shiny as chrome when done rite.

if you want ill post pics of the ones ive finished, rite now im building a '63 corvette pro mod dragster. bout 3/4 done
