I absolutely have had to do that on several occasions with models that just did not go together the way I had planned. I currently have a Modelhaus resin '56 Dodge kit that is awaiting its second go-round. I messed up my first attempt at a 3-tone paint job and interior detailing. After a few days in the Purple Pond, washing and drying, it sits aside until I'm ready to tackle it again. I'm working on something else in the meantime.
Welcome to our plastic playground Richard. You'll find loads of good and helpful fellow modelers here. You should look up the TriState Model Club in NJ for some really helpful and entertaining guys who'd be more than happy to help you along in this great hobby.
