Took some pics of my son Paul browning his barrel with LMF.
It is very critical when applying, to use a light /even pressure, any heavy pressure or rubbing , with come out darker.
I thought it might be important to show the size of the patch he used, the patch has been doubled over,and wetted through both of them.So that when you are drawing it from one end of the barrel to the other , you will have enough solution on it and not have to stop and restart.
The instructions say to apply a coat every 3 hrs then scrub with denim and hot water,helps to even out browning.(the exception is no scrubbing between the 1st and 2nd coat)
This pic shows 3hrs after the first coat, it looks a greeny black colour.
This is 3 hrs after the 2nd coat
3hrs after the 3rd coat.
Will post more as it progresses.
Cheers Bob
