Another Por-15 question

Ok I searched and found a basic information on POR-15 and covering it with primer and then body filler. Has anyone done this?
I was thinking about doing it on my truck where the rust is just more than the vehicle and I cannot replace all the metal.

Is there a way of doing it, right vs wrong.

I put POR15 on spots of rust on a 1984 chev pu.One coat of POR15 and I brushed some yellow paint on top of it. 9 or 10 years latter the smaller rust spots have held up well. The bigger spots have blistered up.I was going to do what you suggested but have heard of peeling problems with POR15 so I sandblasted the rust, used metal conditioner and epoxied it.

As has been said a hundred times here, nothing you do short of cutting it out, will cure rust. POR 15 will simply cover it up! It may seal it so you don't see it for a while, but it is still there, trying to get out.

POR15. The company strongly recommends brushing, wire wheel cleaning, or sanding to remove all the rust possible before coating with POR15. If it peeled, it was probably painted over dust or loose rust particles.

Doing an improper installation is NOT the fault of the product.

Back to the question

So once I apply it can I go over it with filler? Based on the manufacturer yes you can but has anyone tried this?
Thanks

I didn't see any indication of what process was used to prep the area. The problems they are indicating are normal for corrosion.

I like Eastwood Tools Rust Encapsulator Product over POR15

POR15 has no UV protection and has to be thinned with their thinners.

Eastwoods product has UV protection and can be thinned up to 20% with good grade lacquer thinner for spraying.

Both products actually brush on and dry without much if any visible brush strokes.

While it's true media blasting or cutting out and repairing are the only ways to get rid of rust...if you clean any loose rust off and make sure the areas are contaminate free these products do inhibit the rust process - but will not stop it.

The bottom line is once rust starts you cannot stop it - only stay on top of it. Even acid dipping a car will not get to rust between pinchwelds.

I have used the por-15 on one of my cars,and it had a small dent in the door,after I brushed on the paint I than did the bondo job,but took extra causion and scratched it up with a scratch pad to ensure the bite on the paint,than I primed after I put the bondo on and cured,has been sitting out in the weather for 2 years and looks the same as the day I put it on. It was a very lite coat of bondo no cracking.

Strongly recommend against "encapsulating" rust with any product!

It will not last!!!!
