About POR-15 Rust Preventive Coating, Stop Rust and Corrosion Permanently
Overall Feedback:
92% positive
75% liked its quick drying time, but 25% found it took too long
It takes 6-8 hours to dry.
The coating dries to a hard shiny finish that isn't sticky at all. It is recommended to apply a second coat in a couple of hours and allow 24 hours to completely dry.
I had to soak it in a tube with dishwashing liquid and baking soda for a couple of hours to get moisture under the paint so I could rub it off after 48 hours.
81% found it easy to apply
I can apply the product with a brush and it flattens out smoothly.
83% praised the excellent protective coating, while 17% found it wore off quickly
I applied this product to my truck's frame after removing large scale rust.
The rust inhibitor was effective as there was no rust or breakdown on my zero turn mower deck.
The product's shelf life is its big downfall. Once opened, it gets hard as a rock shortly after and cannot be extended.
81% appreciated its long-lasting protection, although 19% found it wore off over time
20 years ago, the product was awesome but now it is total crap.
I feel that the can should be stronger.
I had to go through 3 cans recently because it won't keep and I tried every trick I could find to help extend the shelf life to no avail. It gets hard as a rock in the can very shortly after I open it for the first time.
90% praised the excellent surface finish, while 10% noticed a sticky residue
The coating dries to a hard shiny finish that is not sticky at all.
I have noticed that it does not stick well on smooth surfaces and a wire brush on drill is too smooth to guarantee adhesion.
