Head P&P Question

[86LXItooFAST4me]

i was BSing with a friend one day and we were talking about my car. we got into the porting on my head and he asked me if they ran this kinda goop stuff threw it. i had no idea what he was talking about but apparently there is this type of thick cream with abrasive material that is ran threw the ports some how and is supposed to polish the hell out of it making in smooth as hell.

any one ever heard of anything like this?
