Today, I applied Tamiya TS-13 Clear onto all body colored surfaces. It was risky applying lacquer over the acrylic gunmetal paint (Tamiya bottled type), but it turned out very well.
The can was heated up in hot water and shaken for 2 mins, followed by a quick swirling of the mixing ball around the bottom of the can.
For the mist coats, I held the can about 9 inches away and moved the can quickly.
1st mist coat - very very light, made the paint appear dull
2nd mist coat 5 mins later - very light again, started to get some shine
3rd mist coat 5 mins later - light coat
4th coat 10 mins later - held the can closer by 2-3 inches and paint began to get glossy
5th coat 15 mins later - held the can about 7 inches away and pressed down on the nozzle at full blast. I key of this final step is to have the paint completely wet. Having a light shining while you work is essential to guiding you towards spraying the sufficient amount.
