haha no joke bro, when i read that same thing about "big load" i literatly laughed out loud in the computer ILC building at the UofA, forgot where i was for a second haha, as for me using simple green, i used it because my engine was nasty looking, brown n shit, quick rinses do wonders, what exactly should i cover up though if i do a rinse in the engine? i had control of the simple green so didnt need to cover.
