I started Paint Prep on the chip pan today...
First I completely scrubbed the " HE Double Hockey Stick " out of top and bottom of the chip pan with Purple Power, My favorite goto cleaner. It easily took 1-1/2 Hrs just to get all the Dirt, Oil & Gunk off.
After the chip pan was rinsed & dry I went to town on the rust with my twisted wire brush to knock off all the rust scale & sticker in the center.
I used a scraper to get the rubber coating off the underside and a metal file to remove nicks and burrs along the edges. Then I used Phosphoric acid and scrubbed the chip pan and let the sun bake it dry.. after about an hour I scrubbed and rinsed it. The chip pan came out excellent.
Edit:
To be honest, Looking back on all the work thats been done with these 3 large items... It may have been beneficial to just build an electrolysis tank for them, Before you can get at the rust you have to do a great job of De-greasing then remove Rust Scale then soak with phosphoric acid and rinse numerous times.. Then when thats all done you have to make sure to check for loose paint and by the time your done theres bound to be many spots where the paint is all but gone, really thin and may even peel down the road, as can be seen in the 3rd photo..
Now that you have the Items all cleaned up and ready to prime ( Yes you did a great job..! ) your still left with less then an ideal surface. You bought enough of the best primer to spray the whole project.. The question is do you was to prime a really clean but decaying surface or a factory fresh substrait.
For people that have a very small or no yard this may be the best and only option, you would be asking for nothing but trouble having a tank in your garage large enough to hold these items, which is fine... This chip pan will be in great shape for years to come if you did a great prep job.
If you have the room - Even if the the hours you spend preping the items vs the hrs to build a tank along with some post cleanup were equal, you would be " or in my case would have been " better off I believe going the tank route.. Because you end up with the ultimate prep job - just the pure substrait.
I doubt ill have to prep Items this size again anytime in the foreseeable future... But if I do, there will be a tank involved.
After all the Dirt, Oil, Rust and loose paint was removed I let the chip pan thoroughly dry, I was now ready to prime and paint it, I began assembly of the new HF HVLP pressure pot spray gun so I could knock this puppy out in a single day.
Nope not going to happen - One of the hoses.. specifically the air hose to the gun had a connector different in size from the rest.. which is fine because you wouldn't want to connect a paint hose to the air inlet on the spray gun, except the gun had an adapter mismatch.
I took the sprayer back to HF and showed them, the gal was nice enough and said sometimes these things happen ( I don't know if its just me.. but I've never had any luck with HF spray equipment ) She refunded my money. I didn't get another spray gun because the day was getting long and I would not have enough time to get back and complete the job..
I'll hit a couple of spray shops this week and get a good spray gun and try again next weekend. I'll prep the motor cabinet during the week if time allows.. Maybe ill be ready to paint all three pieces who knows..
LOL I have had a rough time with this whole painting thing from the start... I know I need to use a professional paint on these parts If its to endure another 30 years - I can get away with rattle can paint above the chip pan, but the chip pan and cabinets need to be durable. I intend to win this battle.
