RE: any experience with da vinci brushes

DEAR LIST,
        I have an observation about the "stainless" part of the Magic Brushes. I love them and they coat PT/PD wonderfully. They have a little, shall we say "tarnish" at the bottom of the ferrule where it meets the bristles. It isn't brown or red like rust, it is gray. I learned when mixing my first batch of Pt solution a few years ago that the stainless steel spatula was quickly covered with a gray coating when used to measure the Pt salt. I now use only plastic or Teflon spatulas (obtained from the local university chem. lab) with no problems.
        I haven't seen any bad effects from the tarnish but I just wanted to point out that, even though it doesn't rust, the stainless steel does tarnish.
                CHEERS!

My 60 mm DaVinci 5080 lies here in front of me and on the metal
ferule is embossed: "Edelstahl, Rostfrei". It is attached to the
wooden handle with two 'rivets' on each side. Maybe these are not
stainless? Mine is to new to notice any rust on these rivets or
crackling of the paint. Probably it is a good idea to protect the
rivets by coating them.

It costed me 16 euro's in the Netherlands.
