I would go with Awlgrip if you have a choice , I have used both and prefer the way it lays down easy to work with 
I've never used awlgrip, but I'll be honest, if it gets any easier than interlux brightside then a half retarded caveman can do it. Both products I have heard great things, I can only speak on the interlux brand because that is what I've used my entire build. Mix paint and hardner, add thinner and apply either spray or roll and tip. It's that easy.
