I do that to anything that has engraved markings too. Just run white out or a paint pen across them and then wipe off the excess. Also works good on drill bits.
Good job on the Kreg, hadn't thought about that one.

I always put up my tips here as soon as I receive all of the 'read request msgs' from the mags. BTW, thanks Tom Ferone for the idea. During the shop crawl I noticed Tom's were still factory dim. I figured that if Tom hadn't already done his, then a lot of folks hadn't thought about it yet!
