Paint
Your washer and dryer look great! It reminded me of back when I was in the business. I used "Zynolite Epoxy" Avocado paint and it was a perfect match. It was an oil based enamel, not a 2 part epoxy. It thins well with Naptha, which helps it dry quickly. I had a Binks gun and a true 1 horsepower compressor. It seems that the paint line was made to match appliance colors. The Harvest Gold matches most brands, the White is spot on for appliance white, and the Navajo is good for the off white. The gloss grey is good for the inside of a Whirlpool/Kenmore dryer. In the '80s, Avocado was considered out-dated, and people thought the machines were old. Same was true of Harvest Gold, so I would repaint some of them. I used to sand the machines with 400 wet-or-dry paper (wet), wash them, and paint them in my back yard on a fork lift pallet. Mostly I used Navajo or White. I now have a $14 gun from Harbor Freight and a small compressor from them, and they work great on the odds and ends I sometimes paint. I haven't seen the old Zynolite Epoxy anywhere, but I found that it went on better and looked better than Rustoleum. If I had an appliance that still looked pretty good, I'd use car wax on it to give it an extra shine. Sometimes I would hit it with polishing compound and my buffer first. I never did this to a washer, but I did have the top of a classic stove redone at San Diego Porcelin. It looked like new. I would sometimes get used appliances in San Bernardino, and the washers were usualy clogged with minerals. To clean them, I would fill them with water and pour in about 1 quart of Muriatic Acid, and let it run. I used rubber gloves and a Scotch Brite sponge, and scrub the minerals off of the top of the tub and agitator. I would usually throw out the sponge after this, the acid would chew them up, but the tub would be nice and clean. Best wishes everyone
