Finally had a few days with low humidity, so I managed to squirt some paint on the modified 1710 sheet metal on the 1864 (Metalclops).

I used Valspar (5339-15-6PK) International Harvester White Tractor and Implement Spray Paint - 12 oz., (Pack of 6) From Amazon. Got 6 cans of White and one of Yellow for $42. I got the yellow because it got me above $35 for free shipping so basically it was free.
