So I am working at my uncles fiberglass factory now and getting more hands on experience. We seem to go back and forth on how things should be done and how they shouldnt. I dont know his level of actual knowledge but he has worked with fiberglass for almost 30 yrs. We have a plug that we are wanting to rework to make new molds for a customer of ours. It just has a few waves and dips here and there. I said I could do body work and have them done in no time. (I have a degree in autobody work) I then said that it would be sprayed with an epoxy or urethane primer, wet sanded and buffed and call it good. Hes saying that it cant be done this way. Whos correct? I have thought I have often heard of people doing this with no problems. Hes wanting to try and sand just the high spots with 1200 grit and call it good on the plug. I said this would be to fine of paper to get the waves out and that it would just create more problems just sanding one spot only. He hired me for my knowledge in both composites and painting, but never listens to my advice on anything and its starting to annoy me. 

sorry about the rant

That's my thoughts exactly and where we keeping going around. I say fix these plugs properly and don't worry about doin the work in the mold. I'd rather buff and sand a convex part than try to get in the corners on a concave part if that makes sense. I'm just racking my brain around his thoughts on why to not fix this or fix that.  Most of out stuff is chopp gunned with PE still. They had a bad experience with epoxy products and swear all epoxy is junk. He's very old school and stuck in his ways. I'm really the only person with a passion for composites that works here so I keep reading this forum and learning and other sources to improve and stay up with trends and products. He's about to retire and looking to sell the company. I'm interested but would change a lot of how things are done.
