If I was building a paint both I'd use the bilge pump as used in the previous post.
I think that 3d scanning will definitely help. However one of the limitations has been the necessity to use powder to get a good scan. That is not something that every car owner may not want to have done.
For the most part the budgets dictate what can and cannot be done. The majority if the buyers are just not going to care.
A great concept. Definitely a chance to bring back the joy of building when we were kids. Also a way to maybe use up some parts that you may not use and have some fun.
Two thoughts. One you want to clear everything. You also want to use a pattern to get consistent coverage.
Also you want to be consistent with color coats. Depending how thranslucent the paint is you want to make sure all the surfaces have been painted with even coverage or your panels will be slightly different colors otherwise.
Everyone wins on this. I'm sure the new Revell got more than scrap value, Atlantis got some neat kits, and we get to by them. Its great that Ed Sexton went the extra mile on this. .
