Remedies for clogging might be similar to burr tools that clog. I've read of wax, anti- seize , etc...

Gouging the aluminum is what you want to avoid , but so easily done with a course file that doesn't clog- double edged sword!

Ummmmm... enchiladas !!

Well look at that, my original E41 has two blanks on the top and the one in you photo has one. Wonder which one came first?

Well I'll be dag nabit.  ANOTHER unique thing about early cars. This one is on HLS30 03798. 

Enchiladas Enchilaidis potato potato....

Mine is HLS30 06513, so the single blank is earlier, but not by much. Is that a Canadian car?

I heard that running the file over a bar of soap now and then keeps the file from clogging with aluminum.  Well, actually I heard this technique for grinding disks, but the theory should be the same.  Tube looks awesome...me, too lazy to attempt such a thing.  But, I am smack dab in the middle of polishing a vintage Airstream trailer.  The effort is messy, and tiring for sure...after a few hours, I turn black.

So I tried a bar of soap, and I have to say it works well. There is less pinning and as well the soap makes it easier to clean the file once the pinning starts.
Thanks for the tip.
