Hi Bob.
The videos you have seen are pretty much the way I do it. Don't forget to sand the primer coat if you haven't already done so. Mist coats dry very quickly, by the time the last panel is painted, the first ones should be dry to the touch. It only takes me 10 minutes or so to apply several coats.
I then apply a thicker coat to give an even colour, wait a few minutes for that to flash over and then apply a wet coat, holding the spraycan 10cm from the model, moving quite fast.
After painting the entire body, I wait for about 5 minutes and look for orange peel, applying more paint as necessary to achieve a smooth finish, and let it dry for 10 minutes or so. Some colours such as red, black, white, pearl white and Dark Blue Pearl can dry remarkably smooth without the need for more coats. If not, another wet coat is applied. I have also applied gloss clear as the final wetcoat to good effect.
I would recommend leaving the paint a few days to dry thoroughly before sanding. I've left indentations and fingerprints in paint I thought had dried, but had not fully cured .
I've been using Tamiya spraycans for many years now and after much practice usually apply paint wet enough to dry smooth, but without runs. I'm still really nervous each time I pick up a spraycan though.
You're welcome to pm me if you have any questions. Keep practising!
This is a recent paintjob that luckily required no sanding, using the method outlined above. I still think I'm lucky each time that happens!
