No you just swear like an actor in a Tarantino movie.To be honest issues like the lumpy primer do happen to just about everyone sometime, so you'll come to love Simple Green (you are stateside I believe) as a rescue aid.Over time you'll come to find a primer that you prefer for it's coverage, smoothness and non-invasive "tooth", again its down to trial and error. However if I can make a small suggestion hunt around for Vallejo Airbrush Paint Grey Primer (its a dropper bottle NOT a Can) and you can comfortably use that as a brush on primer, doesn't hide detail, is relatively easy to apply and means you can start a new figure on a rainy cold day, without having to go outside or upset rest of family.
