Ahh but I got cake! Did
you get any cake?

Mowcius - Can you share some insight on painting/tinting acrylic?
No problem

I have tried it not too long ago with pretty good success. I only tried it with red spray as that was all I had on hand.
Anyway here's my thoughts:
Easy to apply (just spray it on) but if you are a bit hasty or not too practiced at spray painting or there is dust on the surface then with clear acrylic, everything shows up (not a lot but a bit still).
Etching through it works well although when I then tried to cut it out (using 5mm), the paint burnt a bit (would be better on 3mm).
Shining light through it was ok but unless you used quite a few coats of black, it would probably still show through it a bit.
I can see it working for some people for specific projects but I don't think it is a very good solution for a commercial product.
