From what they told me, the post process is simply to rinse with water after they pull them from the vat, then wash them down with some sort of a preservative. The guy that took my money said he didn't know what the bath was, some sort of acid, or else they just didn't want to tell me. And the same thing with the preservative didn't know what it was just a product that they used.
The surface has a chromated look to it that you can see in the pictures. After you handle it your hands feel a little oily or greasy.
I plan to wash any lap seams with CRC spray brake cleaner to force out anything that might be left in between then give then a good washing down with thinner and prepsol before I begin the bumping and repairs. Of course the surface will be cleaned again with solvents right before applying the PPG DX579 cleaner and PPG DX520 metal conditioner followed by PPG DP90 primer. That’s probably a bit more than Earl Scheib or MAACO would do.
I was a little surprised to see a 5% tax on the bill, here in Illinois labor is not taxed. And I suppose it should come as no surprise that there was an Environmental Surcharge but I didn’t expect it to be 10%. Other than that I’d say the cost was just a little more than having it sandblasted.
