Milky patches under lacquer coat

[Clive]

I am in the process of finishing off a large tug boat from Mountfleet Models.   I have spray painted the hull with Tetrion red oxide and matt black, and have now applied a matt lacquer coat which has left milky patches when dried.  I am in Devon, UK, where the temperature is around 18c at the moment with humidity of 72%.   I understand that the milky patches are due to trapped moisture.    How do I get rid of these ?

Hello Clive, you can try a hair dryer, sometimes when people put hot plates on a lacquer table top it makes it turn white. I have used a hair dryer for this a few times ,it works for me. Just don't hold the dryer in one spot for to long.. Try it , might work, nothing ventured nothing gained lol. Hope it works,

Ps  Do not use a heat gun, it's to hot.

spray slow dry lackuer thinner over it..... you might have to do it 2 to 4 times you will see it slowy disapear . don't flood it , one pass at a time, and wait between passes till the surface is dry to the touch.
