I'm currently sand blasting all the suspension parts. Can I use POR15 on them?

Also can I use POR15 on the other brackets, etc??

Justa suggestion. If you mix Muratic acid and water in a big bucket you can soak things like upper a-arms, spindles, caliper brackets, sway bar brackets, bumper brackets, etc.. I used a 5 part water to 1 part acid solution. I use it to clean my hot tub filter, so I think it is ok on plastics. Not sure what it'd do to paint.

Nasty stuff, so use chemical resistant rubber gloves. It de-rusted everything so far to a like-new metal finish, requiring minor touch up with wire wheel. Add more muratic acid to the mix when it stops bubblin'.

So far everything I have done this way, air dried then coated with POR-15 looks great.

Any ideas on where to find that Muratic acid?
I'd give it a try.

sounds like a great idea, i know that it's used to clean up mortar so maybe a builder supply might carry it. ques. did you have to neturalize it with anything??
thanks john..

Muratic acid should be cheap and availible at any hardware-bilding-type store (Lowes. Handyman, etc).

I did rinse the parts with water from hose after the soak. Wear goggles! Then just air dried, & touched up with wire wheel like I said. Course all my stuff fit in a 5-gallon bucket (had to turn the a-arms over a couple times).

Muratic acid is just a 10% hydrochloric acid solution. If you can't find it at a hardware store, try a pool supply place. As a side note, you probably should rinse with water to neutralize after soaking.

if you've alreadty sandblasted the parts to bare metal, a good self etchiching primier then paint, por15 works on metal that's rusted and stops the process, por15 also sells a product called metal ready that puts a zinc phosphate coat on bare metal and etches the metal making it ready to paint.

So if I have a rusty frame, I don't have to sandblast it if I use POR-15? I thought that all I have to do is remove the flaky rust and then apply it. Would this work? Thanks.

Shawn, I recently did my frame 69 ss chevelle, I stripped it with a wire brush wheel/grinder, then I soaked the frame with POR Metal Ready and rinsed according to directions. After it dried, I coated with POR15 I sprayed two coats then applied a thrid coat with a brush, (spray helped me get into the hard to get spots. I then applied two coats of POR chassis black semi-gloss. I will say this it looks pretty, and I dropped a rather large wrench on it the other day and it didn't even leave a mark on the frame. As for weather durability I probably won't know for another year or two. unless I hit the lottery before then!!!Dusty

 

[radair]

What do you thin POR with ? I thought this could only be brushed on , I'd like to give it a try . Thanks , Russ

Thanks for all the input. I'm going to try the muratic. I work for Lowe's, so I'll check out the stuff. Thanks again.

i've used por15 on my 69 as well, looks great and wears like iron. i did sand blast the frame first and then coated. be careful if your thinking of spraying, i understand you'll need an outside air source to breath. the only down side i see to por is it's sensetivity to light,but that shouldn't be a problem with the frame.

 

[Joe Y]

Hey Jon, Por 15 has several top coats you can buy that are not UV sensative if you are conserned but most people on this site haven't topcoated their frame.
