Once upon a time, like the mid to late 90s, I bought the Monogram reissued TBM Avenger (or was it a TBF?), anyway, while I was working on the kit, I knocked over a can of Coke(r) and it spilled all over the decals (and kit parts, instructions, etc.). Totally my fault.
I contacted Monogram by phone and explained my plight and offered to pay for new decals. They said that was all right and mailed out replacement decals. I just let the instructions dry out and washed off the plastic parts. I was very impressed with Monogram's customer service.
