Hydro dipping?

My thought is that hydro dipping is a way to dip parts without needing a whole lot of paint. I think that a 1/2 - 3/4" of paint sitting on top of a few gallons of water in a 5 gallon bucket is basically the same as having just paint in the bucket. Chrysler dipped a lot of parts in paint. IMO dipping will provide a thick coating and will easily get into the detailed metal work of a lower control arm for example.
What I may try is putting a piece of saran wrap on top of the water before pouring unthinned paint on top. Then just remove the saran wrap or put something in that will sink it to the bottom. Hopefully the saran wrap will prevent the paint from sinking.
Fwiw I like the fact that dipping is fast and easy. Spraying is fine but dipping is quick and leaves a thick layer of paint without the cleanup and waste that comes with spraying.
