Thompson's was also mentioned but, as usual, but that one was pointed out as being cheaper.
As I said I've not tried it, or any other yet, nor did I read the reviews, as I didn't think they would mention waterproofing clothing!!

I think I spotted a tin of something like it (block paving sealer?) in my dad's garage the other day so might 'borrow' a bit.
I'll give it a careful sniff first!

then try it on an old fishing jacket and see what happens.

Don't hold your breath, it could be a while.
