Technical coatings for parts

The new pistons came from coatings. Piston has now heat resistant top coating (there is something very pornographic to have golden pistons), friction reducing coating on the sides and the underside has been coated with heat transmissive coating.

The exhaust manifold and the turbine housing have been coated with stuff that keeps the heat inside. I chose blue color for some reason, thought it was cool and only afterwards heard that it changes color when heated. I cant wait to see that in person ­čśÇ

Other color choices were black, different shades of grey and red. In the photo below, the color seems bit intense.

Edit: this is how the piston was prior coating – all the sharp edges rounded
