Working on the Kotari 1/32 Spitfire, my go-to MiG masking putty had been all used up so I thought using Blue Tack was a good idea. NOPE. After airbrushing the RAF Dark Green and letting dry overnight I just removed the Blue Tack and horror I see this oil residue left on the Dark Earth color. FML. Anyone experienced this and know if there’s a good way to remove the oil or do I need to strip it all down and start over? So bummed.
