Swinger 1969, testfitting engine and painting is going on

Nice! is that a paint booth? or a home garage setup. If it is a garage, how are you controlling the dut etc. from contaminating your paint operation?
In this same area in my carroom i do all the small parts of doing. That is why there is some visible markings all over. That is no problem! It means that i have to use some cleaning material here.
