This spray gives an excellent colour with a few coats, or over a white undercoat. HOWEVER, it is prone to interference from humidity, much more than your average undercoat spray. It can often take a whole day to dry completely, and does not react well to glue. It will also go crazy when in contact with even the smallest amount of dust, and has a tendency to clog and cake details on your models. If you absolutely need to undercoat your army bright yellow this product is your best bet, but take care when using it or you might ruin your models.
