what are you guys using please.
everything I tried I would not recommend! Just don't last long enough.
On a couple of my fav old hats I now rub some Mindel boot wax into them, which works ok.
I now just use good quality gortex clothes.
Try Thomson's brick seal.
i use nikwax feller wash-in or spray types ,on my old boots i use wd40 stinks like hell but it works and you won't rust
You could make your own wax. Beeswax, white spirit and boiled linseed oil. Just google it. Very good stuff.
Bob, Fabsil paint on is very good.
It's silicone based so lasts much longer than nikwax and the like.
I tried the Fabsil spray waterproofer on my hat , seems to work OK.
It also makes a very nice job of wood stocks, from bare wood to oiled finish in an afternoon, gives a lovely
soft satin sheen, and it's water proof to the point that it doesn't dull or water mark.
My mix is ½ and ½ boiled linseed to proper turpentine, with an equal measure of melted bees wax.
Think it works out out 250ml each of the liquids to alb weight of wax.
