I have also coloured in the stampings on my slide in silver on my 35 and in red, white and blue on my 26. Today, I installed a chrome plated Extended Slide Release, slide lock and chrome pins for the two just above the trigger guard on the 35. Gun got BLING! LOL I don't have pics yet though.
FYI If you ever take the pins out, make sure to put in the upper, smaller one before you insert the slide catch. Then insert the lower, larger pin. I tried it the other way and didn't realize that the spring on the slide catch got in the way of the second pin. It took me quite a while to notice that and correct the problem.
