I prefer black backgrounds, yesterday I carefully applied one i bought that is a
static cling one (spoiler alert: don't buy the one I got).
It took quite a while to get all the bubbles worked out of it, but it looked great when I finished yesterday. All the bubbles were gone. The edges weren't perfect, it was hard to get a clean side cut, but the bubbles were all gone.
Now this morning a see a ton of tiny bubbles across the back. Cr*p!
So now I'm not sure what to do. Contemplating using acrylic paint (liquitex basics water based, which i already have), but need to leak test the new tanks before doing something so permanent. plus I'm time constrained, I have plant orders arriving in a few days, so need to get cracking on other setup tasks.
How many of you have done black painted backgrounds, and what did you use?
