How to Remove POR15 or Equivalent From Metal
 

The previous owner applied POR15 or an equivalent rust inhibitor on the interior (floor and fire wall) of my '57. I want to remove this coating. Does anyone have any experience removing this type of coating?

Why do you want to remove it?
Perhaps you don't need to remove it at all.

If you are commited to removing it, this tool would be very effective.

You could try grinding it, but I think it'll just gum up your disc.

Avoid chemical paint strippers, hell of a mess!

Sandblasting would also work.

I think a needle scaler would be most effective but it would require teaching yourself how to keep the scaler from beating your panels up. I have been using a "standard duty" IR125 for many years. It's amazing what you can do with it.

I am also wondering why you are removing this coating. I'm guessing there is rust underneath that needs repair...

Sandblasting a coating like that off will get very expensive...it's very hard to remove and time consuming...I've had it done before....most sandblasting is done outdoors and when the heat/sun gets on the black surfaces they get soft and the media wont work very good...
I had wondered about taking a small torch and trying to heat it a little(very little) and using a putty knife on mine to see how it would work....unless theres some reasoning for it, like looks or something ,id be inclined to leave it be...

Never understood why POR15 has such wide appeal. I hate that stuff. Just the name should send anyone running away from it. Paint Over Rust? yuck. QBean you have my sympathy. That crap makes a mess.

I second this question.

I have used it but IMHO you should not apply it over rust, only areas that had rust at one time. The pits and ruff surface the rust leaves behind is what allows the POR 15 to bond. If you have brand new metal POR15 is less effective.
