Do you think they will work well on rocks??

I bought these to use on rocks, smooth rocks. They worked good, but when I coated with clear nail polish-as I usually do with regular paints, everything melted and ran. I'm so disappointed. I'll try a regular spray sealer next, but I've always had better luck and a glossier finish when sealing with just regular nail polish-until now. . .

Would these work on a plastic cooler?

I suggest you sand the cooler to get a more rough surface then color over it

What are all the colors included in this? Is the color gray included? How thick/ wide is the line? I am looking for .7mm

Included colors are:Navy Blue, Light Blue, Purple, Forest Green, Light Green, Pink, Red, Yellow, White, Grey, Black, Orange, Light Orange and an Orange Cream color. Line is .9 ~ 1.3mm. The thinnest I've found in actual "paint" markers.

Is this good for painting glasses? Can you bake it on like acrylic paint?

Yes they will write on glass. I have used them on wine bottles. I also use them on canvas and rocks. Not sure about the baking part, never tried that.
