MV Agusta Dragster exhaust rust removal

I'm so amazed how good this harpic works on rust..
Result is just awesome and it only took an hour.

What did you use to remove the rust? I’ve got 2015 dragster which seems to be corroding quite bad in some places underneath

Harpic and some basic cloth or rag..
