what is the best waiting time before masking for a second color
It depends on where you live and what paint you have used mostly.
If you used acrylics, and you have humid weather, at least 24 hours drying time, and I would still advise using a low tack masking medium like Tamiya tape.
For enamels I wait 48 hours, the weather here is humid at the moment and it’s taking all the paints a while to cure.
Mind you during winter here I can mask and spray inside 2 hours with acrylics and 12 with enamels cause we have super cold dry air during winter.
Ditto on what Sean said… take your time and it’s all worthwhile… Rush it and you’ll be stripping the model to repaint… (voice of experience… [V])
thanks for the tips!!!
