Many have had problems with Vallejo surface primer,me to,Dry Tip problems and if you have to sand you are in trouble,I live at the tropics and wet or dry its always hot and Stynylrez is the only Acrylic primer that has not given me problems in any situation directly out of the bottle, I gave the Primer to my Millenium Falcon 1/72 which is very large without having to clean the tip even once…and if you are new with the AB the badger is very forgiving.
But as FirstCircle say Lacquer Primer are always the BEST,very durable and they bond with the Plastic,but you need good ventilation etc…
