We need to paint a couple of rooms at our house & I had planned to buy the "grizzly" brand of paint , simply because you can get it with the primer already in it. I do have a question though for those who have used it. I have a fairly dark colour in my bedroom - dark raspberry. Will a lighter colour in this paint cover in 1 coat or will I still have to do the 2 coat thing? One coat I can handle, 2 overwhelms me...
