klox, i have a can of tapmatic "dual action #1" fluid that i have not tried yet. however, on the can it says that it's for all metals *except* aluminum. do you use a different type of tapmatic for aluminum, or is this stuff actually good for Al?
i also have a can of castrol moly-dee tapping fluid that i guess i could try as a cutting fluid for aluminum. however, it looks just as messy at first glance. |
