If you are working from plastic parts that is really tricky but it can be done. You will have to use a release wax and I (personally) would use PVA (polyvinyl alcohol) as a spray release. It is tricky to spray and must be applied in several thin coats but it releases very easily. You probably won't have to make molds. If careful you can make fenders off of your original parts. They will be a bit larger but shouldn't be enough to matter. I have made molds for 25+ years from just about everything there is so if you have questions, just ask.

Thank you! I think I'm going to try some tests this weekend
