I have used Castrol Super Clean with excellent success (and if I recall I got the link about the product here). Anyway, I have recently purchased some Kato SD40's and plan on stripping them for GTW repaint, using the Castrol Super Clean. But I have yet to use the product on a Kato shell.
Anyone with first hand knowledge ?? (oh my locos are N Scale)
Thank you in advance for your time and response.
