Paint Q?

[MarkII]

The cold has nothing to do with the lack of a shine by the way it was probably just put on to dry

at -10 to -16 with out right heat it would fade, i'v been painting 12 year lad. by adding the thinners to last coat it reduces that dry coat effect and gives a nice wet looking shine.
every paint will f up if used below a certain temp. dampness infects the top layer resulting in dull finish.
