Better than wax over strike anywhere matches is to spray or dip the matches in varnish. Wax can rub off, but varnish impregnates the wood, making the matches permanently waterproof. Before I started doing this, I had matches just smoke and go out because they had absorbed moisture thru the stick.
As well as these matches, I carry a Bic lighter and a metal match in my survival kit. You just can’t have too many ways to start a fire. Also try a plastic film can full of calcium carbide (for miner’s lamps in the old days). Put a t-spoon of this in a small can with some water and build your fire over the acetylene gas it releases. Works even in the pouring rain.
