Help! Vinyl won't stick to a painted wall!

[FireSprint.com]

I have seen this thread over and over again, and while I have seen many answers, I feel like 3M has created a definitive guide (Bulletin 5-37) and a accompanying video to help answer the question Will it stick/Why doesn't it stick.

I wrote a blog post to bring most of the information into one location: https://firesprint.com/blog/index.p...e-vinyl-signs-stickers-and-decals-will-stick/

Thank for checking it out!
