Has anyone ever heard of glass beading their piston domes, I have been told that it may be advantageous but have not be given any explanation as to why this may be. Please let me know if you have any information on the subject.

Thanks, Mike.

 

it basically just cleans them. i got my **** vack from the machine shop friday and when i took it in their they asked me if i wanted to clean the pistons up. i ask how they would do that and they said glass beading. i didnt do though. i just took scotch brite to them and deburred them. i could be wrong tho.

 

I always polish the piston tops, to minimize carbon formation. Several piston top coatings are available, but I've yet to see proof of any improvements made...
