Ali panels sharp? Use one of these link here

Got one already, its a de-burring tool, quick and easy to clean out the holes you just drilled in the ally panels... A godsend when you have a few hundred holes to de-burr... ie when putting on the body panels..
Yup a definate Godsend.....Along with the Clecko's

Another one. Its dearer but the curved one gives a good finish and the bits store in the handle. I'm a sucker for a gimmick.

I have used one of these for years... blades are a bit expensive to replace but worth it!

I have one at work i might ask if i can borrow it when i need one
