Revell 71 GTX seems to be my unicorn. It was one of the first models I have started building and everything it was nearly complete I messed it up.
When I originally built it, it was about 99% done and while doing the last touch ups I accidentally spilled testors glue on the roof... I have repainted it at least 5 times since and every time I paint it, I either decide that I don't like the color or I mess up the paint... so far it's been painted red, yellow, gloss black, and flat black... it's even been fully rebuilt and for some reason this time around the hood doesn't fit...
After about 3 years on and off working on it, I decided to put it inside the box and get a new model kit of that car, hopefully that one isn't cursed...
