Lidded cans in the 1/2 Pt. (?) sample size. I did the same thing at Lowe's, a Quart of matched paint for the high heeled, platform feets (cooling vent access on carpet) hack for the Q700 triplets.

For spray application, either store should have compressed air canister type, refillable spray bombs for the mixed paint. Experiment with foam rollers, they may add an acceptable substitute texture process for your front bezel.
