exterior color match siebenrock to BMW head?

Here's a response re: the short term look ...from George Strong in the UK. bmbikes forum.

Barrel fins seem OK with the silver leaf rub'n'buff even after prolonged heat - doesn't look any different after about 500 miles. Same with base of barrel and crankcase ... I'm still on the first tube after covering everything alloy, with a spare on the shelf.

Unfortunately, that doesn't tell us anything about the higher heat application of the heads. Course, if jj tries it, they we can ALL find out!

My guess is that not many will try it on the heads, or the barrels, as it'd be a tedious application rubbing it in down amongst the fins. I was surprised to read someone had had a go at the barrels. I think he used a tooth brush to apply it. I doubt I'd have the patience.

Just an update. I had the heads vapor blasted and i think they got pretty close to matching the Siebenrock cylinders. It appears to me the cylinders are painted a bit. I wish Siebenrock disclosed more information (in English) about their materials.

check out the vapor work:

They look spectacular, and better than the new barrels, but near enough for it to look great.
