Great question — answering as the UphillTech team:
I know this site is for 'hacks' but I wouldn't hack an expensive wax jacket. Do an Amazon [or similar] search for "wax for wax jacket". Everybody who makes wax jackets, from Barbour to Fjällräven, and even some who don't make clothing but only make clean/protect products have one. I'd get one I've at least heard of, Barbour, Grangers in the UK - likely different by territory - even if they're more expensive. [BTW, don't cross-type, ie don't put beeswax on a regular wax jacket - they don't combine well.] …And don't just buy some random wax type. You wouldn't put shoe polish on your car, or car wax on your shoes. Don't do it with wax jackets either. The wax needs to be readily absorbed & stay...
