I had an airbrush malfunction (my fault) and need to strip Vallejo grey primer off a few parts.  Anyone have any suggestions on how to do this.  So far I have tried warm soapy water, alcohol, and Castrol Super Clean.  So far the primer seems to be resisting everything.  I also tried fingernail polish remover and it worked, but I'm afraid to use it on small delicate parts.

Thanks

Don
