Rust on stainless downpipes

[darrsi]

Hell of an improvement for little effort. Impressive.

Yeah, took me no more than 30mins in total with no hard work involved.

I forget to mention before i used a black bin bag to cover the engine behind the pipes and taped it up, if it does that to metal then i can only presume it's not too friendly on paintwork.
And i used a pair of washing up gloves for a bit of extra skin protection along with safety glasses.
You really don't want that stuff in your eyes!  :eek
