Hello, here's hoping this will settle it.
Rain hits trees all the time so the sprinkler is not going to harm your tree's bark. Any wrap, spray, or coating will certainly do more harm.
I would recommend making sure no mulch around the tree touches the bark at the base. Mulch does a great job of keeping moisture in the soil but when bunched up against the tree's base, it makes for a great environment for fungi which can lead to rot. Keep it a good half foot away from the tree.
Good-luck!
