Boiled linseed oil can self ignite on a bundled rag so be really careful, bushbros!
I used petroleum jelly and... uhhhhh... *sneaker-netting!*... beeswax, danged if I can remember where the recipe came from
and scaled it up for Barbour thorn dressing...
1oz Beeswax to 5oz Petroleum jelly, I used 4oz beeswax to 20oz petroleum jelly melted together in a bain marie in a 1.5l pyrex bowl. It did a big curtain fabric cotton cloak (full length, half circle- and- a- bit) but I should have applied another coat. It was a complete PIA to brush in and it ideally needs warming as and after you spread it to get it distributing evenly
It added a considerable weight to the garment!
Coincidentally, I used the brush afterwards on my oak spinning wheel and then, all the rest of my wooden furniture as I found its an absolutely beaut polish
Buff off well afterwards though as its a bit sticky.
BTW I bought the petroleum jelly from an animal feed supplier (its used as hoof dressing) and the 1oz beeswax off the bay, MUCH cheapness
