$20 at Harbor Freight gets you a shiny radiator!
 

Ok, maybe not a whole radiator, but a polishing kit that works great!

I bought this kit today, http://www.harborfreight.com/14-piec...kit-98707.html. It's $19.99 and I used one of the 20% off coupons that are literally everywhere.

I spent about four hours with my drill in the garage polishing my new aluminum radiator I got from Summit a few weeks ago. The results are spectacular. It's hard to tell in the pics but it it's literally a mirror finish on the side tanks now. I paid $200 for the radiator from Summit, it's this one http://www.summitracing.com/parts/SUM-381325. The Be Cool polished radiators are like $800!!

Another plus for Harbor Freight!

That looks great. I'll keep it in mind when I get to that point on my build. Thanks for the info.
