I masked off the cockpit with 3M blue painters tape before I sprayed the Hellcat with Tamiya rattle can sea blue. I am going to be holding my breath when the moment comes to remove that tape. I'm hoping my masking is effective and that the cockpit, which I have to say, came out really nicely IMHO, isn't ruined with bleed through. The tape looks okay, but until I see for sure....fingers crossed
