It may be a bit early to be thinking about summer and rain (although maybe not given the mild winter). But I'm curious what folks do for mitigating rain, bugs and critters from coming into the stove and pipes via their cap? Personally I was thinking of some sort of waterproof or waxed canvas material with a shock cord base (would look like a shower cap). We are up on a hill so my main concern is wind blown rain coming down my pipes and rusting things out.

All ideas welcome
 
It rains all year here. My chimney is stainless and has a cap, water doesn't seem to bother it. Bugs don't seem to be a problem, sometimes birds are I've had them get into my stove.

I use an old pillow case, wrapped around the top, and its thin so it can breathe. I never had anything get into my flue in 3 years so far.

Mine all have stainless caps. No problems with birds or water. For some reason, wasps like the cap for my fireplace insert. For this reason, I clean the chimney in the spring. In the fall, I quickly stuff some crumpled up paper bags in the stove and light it with a propane torch. If I take my time putting in kindling and wood as normal, the wasps quickly investigate where the change in air pressure is coming from. Nothing like uninvited guests in the house to ruin a guy's day.

Stainless steel cap wrapped in wire mesh with 1/2'' square holes, no rain, no rust, no birds, no debris, no leafs, etc, etc..
 
I place a chunk of black plastic film (think garbage bag) over the opening, then twist lock the cap back over it. My cap is an open design and I don't want the little birdies to fall in. Don't forget to remove it upon first fire!

Do you think that metal garden fabric, (has tiny holes for stopping mice etc) would work ok? Our roof pipe/rain cap sits at a slight angle because of being on an RV roof, and lots of rain is getting in and rusting the stove top. The installation appears to be fine. Would rather avoid buying another rain cap.

Definitely no. That would clog up quickly which could be a near instant disaster. The chimney and rain cap should be plumb level. If you can post some pictures of the inside and out we may be able to spot issues.
