You guys are missing my point!
Mercedes engineeers have used the latest technologies. Now look at new production 606 engines- they don't use tin coated pistons skirts anymore. I'm going to use a coating, that is more inline with current engineering practices-not old practices.
The advantages are simple- tin is a break-in coating. The applied coating will keep oil, lower friction, and cause the skirt to run closer to zero clearance. All will improve ring wear, cylinder wear, and you should hear a huge reduction in the diesel ignition piston slap.
I can apply molycote myself with minimal cost, hence the desire. Yep, if it comes loose- it will be ugly.
Coatings are common- not only in racing, but in all the industrial diesel rebuilding too- catapilar comes to mind.
