Disco 58 has shared with us his claim on the Dumbass Award. He seems to be somewhat embarrassed about his misadventure. However, I have to say that he's not alone. I don't think that anyone is every going to walk away with that Dumbass Award. There's always going to be stiff competition for it.
So what has been your modelling disaster that qualifies you for the Dumbass Award?
I tend to mask things in a mirror image of what they should be. The dark camouflage colour ends up where the light colour should be. I've done this numerous times and despite thinking that I've double checked... I've done it twice with 1/72 F-4 intake splitter plates. That isn't the end of the world and is fairly easily rectified - it's just annoying when I realise my own stupidity. However, I once did it with a 1/48 Spitfire!
But that's not the dumbest of dumbass things that I've done. Once I was building two 1/48 Bf109s in parallel, a G-6 and a G-10. The G-6 was in a standard 74/75/76 scheme, with the G-10 in a 75/82/76 scheme with a multicoloured tail band. I spent three days spraying these. I worked really hard on the mottling and was justifiably proud of the results. I varnished them and prepared to apply the decals. It was then that I noticed something slightly odd. Yep... The G-6 was wearing the G-10 scheme, and vice versa!
Dumbass!
