@eb801, thank you, Eric. I agree, thinning Vallejo Model Air is still needed, sometimes I even go for a 1:1 ratio with thinner and do add some drops of improver as well. The clogging is also what ?I face from time to time. Might try some other brands as well to get different opinions.
@gblair, thanks, George. Might be difficult to observe on the upper surface indeed.
@lgardner, thank you, Louis.
@fiveten, thanks, Spiros
