Gentlemen,
Thank you for all your replies, as I hope I explained only asking from an interest point of view , as I am old enough and soft enough to have tried all the concoctions. Tru-Oil does stand the test of time and frankly many Professional Gunsmiths whilst shrouding their finish in smoke & mirrors with a dash of dragons blood actually do use Tru for quickness.
An internet search brings up various percentages and ratios , but it would be nice to actually have an educated guess at the Tru constituents.
Lagopus we both know that our concoctions work well and if you would like to PM me it would be appreciated. Have you got any projects on the go at the moment?

P.S. I have tried Linspeed and frankly I am not very impressed at all.
