I recently did a test to see if I could paint a body in one hour from start to finish using tamiya paints. The paint I chose to use was TS-45 Pearl White over tamiya white primer. As stated, all painting was done in a 1 hours' time giving 15 min between coats. Body was first cleaned up removing all parting lines and flaws. It was thoroughly washed with joy dishwash soap. First light coat of white primer was laid down Waited 15 min. Sprayed the next coat of primer with a good cover coat. Waited 15 min. Sprayed the first light coat of pearl white. Waited 15 min. Sprayed the second and last coat of pearl white. Let it sit overnight. You can handle it all you want at this point. The results of my test were very pleasing. Here are a couple pics of the outcome of my test. I could have put down the clear coats, but decals were in the future. Next time I will put down the clear and do the hole paint job in 1.5 hrs and see how it turns out. I waited 5 day's and put some decals down. No clear has been applied yet. As you can see, the paint job came out almost just as good as if I spent a week doing it waiting for paints to dry and sanding between coats of primer and color. I don't use spray cans much anymore as airbrushing is now my norm. This was just a test and your results may vary. As a side note, I feel tamiya spray paints are the best paints to use if you are using spray cans.
