Hi I wanted to build the dash and door panels out of fiberglass. How do people do that with tvs in it and stuff. I have the stock panels and dash. I also have had a lot of experience with fuberglass but have never learned how to do this. So, if anyone can help me out I would really appreciate it.
The way i think I would do it is take the vinyl covering of and cover the plastic with fiberglass after I build the box for tv and everything. Is that how people make it. Again I am not sure, this is just a guess so if you have any experience doing this and can help me out I'd really appreciate it, Thank you
