Is the por15 stuff good for brushing on the underside of my car and on the floor and trunk pans inside the car, And how should I prep the metal before brushing it on.And also does it stop rust from spreading? Thanks.
ya you can brush it on. I would sandblast but if you do not have than a wire wheel on a side grinder then sand untill your satisfied. but to me it sounds as though you have some surface rust i would sandblast it off even if you have to rent a sandblaster for a weekend.
I just have a bit of surface rust in the common spots ( frame rails, trunk and floor pans) places like that, I was reading on there website and it says that it stops rust and even fills pin holes, just wondering if it is true ? thanks
Like azz7772 said I would try and remove the surface rust i.e. 4 1/2" wire wheel on an angle grinder. You would have to be able to get to both sides of the surface to seal it from spreading. I brushed it on the RR and you can't tell it was brushed. Forms a very hard plastic like coating. I plan on doing the same with the Dart. Also the sealer is not UV friendly.
I suggest you use their MetalReady for prepping surface. Its basically phosphoric acid and zinc. After a couple minutes, the acid etches the metal and the zinc bonds to the metal. Just rince off to neutralize. Worked great on my floor pan
