I have been following the 1 oz per quart of mixed paint for many years now. To be honest, I don't actually measure the activator but guesstimate the amount needed. Especially when mixing small amounts.
The benefits include more chip resistance as well.
When cutting and buffing this Mazda, I broke through the clear on the right fender. It was a small area about 1 1/2" wide and 3" long. This was the first time I took a chance and just shot some more clear over the area. Started with just enough to cover the burn through, then a little larger area and then the entire fender. You couldn't see it no matter how hard or from what angle you looked. I was a firm believer in activating base coat after that.
