Stripping black finish off of 2017 engine case and cylinders

[Greaseball_imp]

I talked with the owner of a local vapor blasting service. He uses a mixture of approximately 80% water and 20% glass bead media. He thinks that should be able to get the black finish off of the engine, including the cylinders. The tricky part would be sealing off the engine completely. He's done it before but does not guarantee that the plugged and tapped off items wouldn't get dislodged in the process. It's my risk. Some of his customers have kept their aluminum pieces looking food with wipe-on protective coatings. Or, he could use more blast media in his mixture to give the final surface more tooth for painting. He estimated approximately $200 to $250 for his service.

Bottom line, it looks like I have this process as an option with some risks involved.
