Freds 73 Scamp restore on a budget

Been painting interior parts the last few days and it was tan and white before so takes a bit to make sure I got everything painted good. Used a water borne cleaner and a scratch pad to clean the parts then an adhesion promoter before I put the paint on that was made for plastic and vinyl. I'm kinda hopping it works well and holds on good because I just can't afford new interior trim and doesn't fit as good as factory I think.
