i use chalk paint all the time so may I let you in on a big secret? You can make your own for dirt cheap with a little bit of calcium carbonate and any paint you choose. I get my calcium carbonate at the local ceramic supply store. It's also known as "whitening" and it really is inexpensive. Also, no need for expensive special waxes and brushes. I use Johnson's paste wax and whatever lint free cloth I have on hand. Also, even though it says you don't have to do any prep you really do. A light sanding followed by a wipe down with a tack cloth will go a long way towards a nice finish. Unless you like your surface to have chunks in it from imperfections that were allowed to remain. I prefer a smooth surface even on my distressed pieces.
