That's really messed up, Harry! I LIKE IT! Reminds me of Rock Sugar, Jess Harnell's band.

^{These are a couple of older builds, at this time the only Tuner cars I have completed.}

^{Believe it or not, both of these cars are actually painted with the same color, a 60/40 mix of Kiln Red and Alumacoupe Yellow, only difference is the base and what color Pearl-X was added to the mix. The AE86 is based with Allis-Chalmers Orange and has Copper pearl, the GT-R has a buff primer base and Gold pearl.}

Jim, The Bondo brand Spot & Glaze putty you show here does not use a hardner.  It will set in minutes right out of the tube if used as intended, thin coats.  

Here's a pic showing the MPC, Revell, and Monogram cabs together.

The MPC and Revell cabs are from original issue kits, the Monogram cab is from the recent GMC kit with the plow. Note how much larger the Monogram cab is. The MPC and Revell cabs are pretty close to the same size, with the Revell being slightly narrower, which messes up the proportions of the greenhouse.

I'm thinking this is a colossal blunder on their part

Agreed 100%
