 I think Eastwood sells a paint to look like phosphate. I have seen the results and you can tell it is painted.

Edit:  Mike, you beat me to it..   ;D

There are paints that look like phosphate.  Eastwood is one company.  Phosphate is actually a chemical reaction and it creates a protective layer over the part.

very informative link. It looks like the results can vary a bit, and it takes playing with it a bit to get the amount of sheen you want on your end product. Have you tried this little phosphate experiment yet Darrell?

On their website it says you have to heat to 210 degrees, are you placing the container on the stove, and then dipping? what was your process and can you post a pic of your results Charley?

I have and it does take a little while to get the results you want.

Easy to use and cheap.

Charley, I do not see that the Palmetto is much different than the Phosphate Prep & Etch..  You use the same basic process..  Am I missing something?

I've everything ready ,and my products from Palmetto ,just have not had a chance to get out there. The quarts net a lot of product ,which per Scott can be re-used. The Manganese is mixed in more concentration than the phosphate ,but is said more durable. Hence the use on hood hinges/springs. He sends out an instruction sheet and personally answers any questions ASAP. Like one of the Mustang guys posted : dollar for dollar way cheaper than paint with correct results.



I plan on using a hot plate for small items.

I use a small one burner hot plate and a set of various sizes of SS pots I purchased at Walmart.    and the Palmetto chemical.  For small/med amounts of water, the hot plate works fine and heats up within a few min, but I tried once with a 3 gallon pot and I'm not sure I ever got to 200F using the hot plate.   I think it will be better to use a propane heater for larger amounts (and do it outside) - another use for the burner/stand taht I use for my turkey fryer!).. :)
The Process is:   1) heat water to 200-210F, 2) add appropriate amount of chemical, mix, then 3) submerge the part(s) - I generally try to circulate the solution or the part while it's in the bath.  4) upon removal, wash/dry parts in WD40 (3 times).   I generally spray down again with WD40 and put the part in a plastic ziplock bag until I'm ready to install.

 I have only used 180-190 temps for phosphating. You don't want to start a boil or else you'll start to get crush developing in the pot and that is hard to clean out. I learned that the hard way until a gun restorer showed me that 210 is too close to boiling and after backing it down to 190 things went much better.
You will also want to use a diffuser under the pot to prevent hot spots from developing.

I agree Mike.  If I get close to 200F, I'm happy with the temp.   What do you use as a diffuser?

Cook....All I know is Palmetto was the first guy I found selling it years ago and he has kept it cheap and simple to use. You can get a stainless salad bowl or stainless pot at someplece like Walmart and cook bolt soup on your outdoor Gas bar-b-que.

 I have a small pot with a copper bottom plating and for the larger pot I have what is called a 'stove top heat diffuser' I bought at a dollar store. I have seen them for sale on Amazon too.

Yep, turkey fryer works very well and you don't want to get much higher than 190.  I use a shallow SS serving pan or a porcelain finish cooking pot.
