I just sand blasted my upper and lower control arms and would like advise on using POR 15. Is priming required, one coat or two

I just did my control arms last week. They turned out real nice. After you sandblast make sure they are clean, no oil, etc. Next take metal ready and spray on. Keep this wet with the metal ready for about 15 minutes. After that is done rince them real good. Let them dry then rince them again. After they dry you will see a light powder film on them. You need to get this off. Once you clean it two or three times let it dry completely. Then take a small amount of Por out, careful not to get anything into your original can or its toast. Cover it with sandwich wrap bag and put your lid back on. I used a real fine brush to put mine on with. I tried the foam but they don't last very long as the Por eats it up. Also make sure you wear some breathing protection, this stuff is bad. I have some pics if you would like to look at them. Good luck.

Just note that when 65_Malibu states to "wash" them he means to rinse them. No soap, no cleaner, just water.

No primer needed as thats what the metal ready etching liquid is for.

Also, Metal ready is re-useable so I recommend pouring a little out and brushing it one. Thsi way, you dont spray and drip off the parts. Youc an brush it one and then re-use whatever is left in your application container. Just use a piece of cheese cloth of sumpin' to strain it back into the spray bottle. Im cheap, I guess, so this was good to know as I wanted to stretch this stuff as far as I could.

While we're on the POR 15 subject, is it really the "miracle paint" they make it out to be?

Hopefully I will be blasting the entire frame of my 67 later this year. Is POR 15 the best way to go if durability rates slightly more than looks?

I coated my battery tray with it four years ago. Four years of lead acid fumes and an occasional rinse with anti-freeze from my overflow fitting did not affect the finish one bit.

i am going to say something you are not going to want to hear. i have contacted POR-15. they told me that the best possible adhession you can get is over rust! they told me i could use metal redi, but the best way (cringe)is to spray your freshly sanblasted parts with water and let a light film of (oh-no!)rust form,scoch-brite it,wipe down and apply over rust.

Yes, putting it over rust directly is the best way (Why? I dont know)... that is direct from the company. I have used it on tons of parts and they all look like the day they were painted 3 yrs later. The only thing that will destroy it is brake fluid... had to redo my a-arms after some leaked out of my caliper line.

Sunlight will kill it too. I didn't topcoat my boat trailer that is painted with the marine gray POR-15, and it has turned funny colors and rust is seeping through it. Most of my problem has to do with the sunlight, and the rest is due to only having one thin coat in some areas. I will use POR-15 to recoat it one of these days. Axle and brake backing plates show no signs of trouble with the chassis black since they are underneath the trailer and don't see the sun.

There's something to do with the moisture in the rust that helps the POR grab onto it better or something. Might have something to do with the extra "tooth" you get with the rougher surface too.

Clean it with phosphoric acid before you POR it.
