| As Richard says I have used Tamiya sprays and never had a problem but I do put a lot of care and attention into the process.
Just remember all the basics such as shake the tin for a long long time to ensure a proper mix and I always dip the tin in warm water as well to slightly increase the pressure, help the mixing process and helpt the paint to dry a bit quicker. Another point is to ensure that the surface is properly cleaned and degreased. I always wash the parts in warm soapy water before spraying to ensure it is clean and free of grease and release agents.
Finally make sure you are spraying in a nice dry atmosphere. Sheds can be prone to condensation issues that can affect the surface of the plastic and make sure that the model and the surounds are the same temperature. Taking the model from a warm workshop to a cold shed to spray will cause condensation to form on the plastic surface and affect adhesion.
If you are doing all these points I am not sure what else to suggest but let us know how you go on and maybe a bit more detail about exactly how you spray a model.
I think the Tamiya sprays are superb as regards paint quality, finish and convenience and I have always been pleased with the results.
