Interesting timing here. This morning my paint supplier was just telling me that she will very shortly be unable to get oil based porch and deck enamel. One supplier is pulling quarts off the shelf. Another no longer sells quarts and has told them gallons won't be available much longer.

Varnishes and other oil based products are next on their list. She said she didn't have a time frame but shortly she would have no oil based products on her shelves.
