Our own airbrushing guru, Hank, purchased a number of the new Vallejo Metal colour paints. He says: the paints needed thinning with Vallejo Airbrush Thinner. The gloss black primer worked okay, he found it only achieved a semi gloss finish and he had fish eye issues with the paint. He tried it with his favourite, Tamiya Gloss Black and said it worked very well. He said it was dry enough to continue with his build in about an hour. The caps on the paint seal nicely and the quantity in the bottle was considered good value for money.
