I gave up on being insisting on that
I used Varsol again (mineral solvent), I diluted 1/1 with synthetic enamel, and I applied with pressure of 22psi, was good, to hope to dry 12 hours and to pass sandpaper 2000, to remove the dust.
I pass evil of health, when I use thinner for lacquer nitrocelulose, and it always attacks the plastic of the kit, and I don't feel also calm using that product.
In my country the own thinner for the hobby are expensive, we see her with that he has.
I use testors, revell, and common enamel of painting gate.
