Ya, I experience the same dilemma with you guys. I can only spraying the models in my summer holiday. I have school basically through out the year and have tons of exams and assignments. And you know, the tamperature in Toronto, Canada has started to fall in this week. So it may not be a good idea to paint the models any longer in this year.
What I did in this summer? I put layers of pink primer on all my ferrari kits, and hopefully I can put some SIKKENS AUTOCRYL in next summer.
