I asked about this over on Facebook and on the EAA forums, but got very few responses. It seems to me this might be the place for opinions and experience.
I have made up nearly all the fittings for the wings on my Corben Jr Ace (Baby Ace model E).

I am looking specifically at ways of marking the spar fittings and strut fittings for painting. I was wondering about using a number stamp and lightly punching in a part number. I feel like I saw a picture of a homebuilt with numbers stamped in some part, but wondered about the risk of this causing stress-risers or something. Is this a viable option or no?

Wiring stamped aluminum tags to the parts before painting was suggested and I will go that route if there are no better suggestions, but I would like to permanently mark the pieces if possible. The fittings SHOULD be interchangeable, but theory and practice don't always align.


TLDR Summary:

Can I safely stamp part numbers into my strut fittings? (1" wide .090 4130)
Is there another/better way to identify parts through painting?
How does everyone here mark their fittings from creation through installation?


Thanks all!
