Had another good day in the garage. I detailed a few remaining items on the engine and it's ready for paint now. I'm not sure when I'll be doing that.
One of the things I learned about while resorting Chevys is how to phosphate. It's very simple, basically if you can boil water you can phosphate. Most items on the car like hardware has a phosphate coating. I found a company online that sells supplies called Palmetto Enterprises, he sells zinc and manganese phospate concentrate. Cost are around $25/pint and they cut at 14oz to a gallon of water, little more solution needed for zinc than manganese.
I spent all day doing this, time is the prep like anything else. The glass bead cabinet was running hard today.
Supplies:
Hot plate - $10 @ Walmart
Tongs - $3
WD-40
Candy thermometer - $5
Vessel - glass, porcelain, or stainless. I found an old glass pot from the '80s.
Measuring cup
Phosphate concentrate
Instructions:
1. Bead blast items to be put in solution. Instructions say only allow 2-3 hrs between beading and coating. Metal needs to be fresh for chemical bond.
2. Start with water and get that to almost 190* then add phosphate concentrate.
3. Maintain vessel temp at 190*-200*
4. Add parts. When fizzing stops give it a few more minutes. It seems like 5 minutes is the time in the bath.
5. Remove parts and soak with WD-40. Wipe parts and repeat again.
That's it! You can do this in your house, there is no odor. I like the setup in the garage so I can have an assembly line going. End result is brand new looking hardware that was born with the car. No need to buy all new hardware if your willing to take the time.
Most everything is supposed to be zinc phosphate, that color is a lighter gray to the brown side. Manganese is a darker finish but it's really close. I used manganese since I had that left over. If you pull parts sooner rather than later they will be lighter colored.
Started with fender hardware, these were Evaporust'd first to see what finishes were on them.
