Following on from the Wipeout thread; I've seen a lot of commentary on the American forums about Kroil and JB Bore paste.
From what I can gather Kroil is a penetrating oil (think WD40 if it really worked) which is intended to penetrate and lift any gunk including metals and the notoriously difficult moly, the paste then polishes it out.
No need for bronze brushes.
Brownells sells them as a combo but won't ship it here as Kroil is considered naughty stuff. Otherwise, Kroil doesn't seem to be available here and the closest alternative seems to be Plusgas but I can't actually find out what it's made of.
JB paste I can get from JJK or ebay.
So, does anyone have any experience of using Plusgas?
