Replying to Truck help

So I'm doing a few upgrades on my truck I just got and the front end had barely been clipped and the hood got a few small chunks taken out of it so I'm wondering how to patch that up. It's a fiberglass hood. Should I use like tiger hair or like what types of body filler should I use? I can post pics tomorrow. I also have a few little rust spots on the door jamb that need to be redone so any recommendations on products would be nice. Looking to get this started or possibly done tomorrow.
