HEy everyone, im a 15 year buildier and im fixing to build my 1st glass aircraft. I have 2 combat model pusher jets that are foam. You glass the entire jet and im wondering how to make the panel lines come out. I have heard about taking a pencil and marking them then putting a clear coat over to protect them. So if anyone ahs any technics or pics to show me how to do this I would really app it. Thanks
