As I was cleaning my car I have noticed a few stone chips on the bonnet and some how above the drivers door

. Anyway I went to Autobarn and asked for some touch up paint, basically they would mix me some based on my color code and have it for me in either a tin or spray. I just want to know would it be better to get in tin (using fine brush to apply it) or look around for an actual touch up pen (and would the dealers have anything like that)? Either way I really want to hide these chips asap. Also is there any special way of applying it? Or just basically dab a bit on, dry it with a hair dryer and maybe do another couple of coats? I have heard people applying the paint then using clear nail polish to bed it in there!!
