POR-15 46804 White Top Coat - 1 quart

Not quite the same paint as POR-15 Rust Preventative paint Black. I understand the need for different final coat colors, especially when needed for UV protection, but this stuff is a different paint than the original POR-15. As others have noted - this top coat flows in very strange ways. In some ways it seems like it continues to flow for many hours, so when painting any vertical surface with it - be careful as it will continue to flow, drip and run long after you think that you have brushed out a nice smooth surface. Like Black POR-15 this settles and smooths out fairly quickly, so it is great for hiding brush marks. The issue is that it does not stop flowing for many hours. I was painting a large steel tank 14"D x 45" long and so I used original POR-15 to cover all rust spots and bare metal. That paint has it own very unique flow qualities but I have used it long enough to know how to use it. Also know that within a couple of hours it has started to dry enough to stop flowing. But this White Top Coat is different. I VERY carefully brushed it out so it was applied evenly and it looked great But then hours later I check it and it was full of runs & drips. So be very careful when applying to any non-horizontal surface. Also believe that this white Top Coat has a different chemistry, as you can thin it and clean brushes with regular Mineral Spirits. No way with Original POR-15 Black which is almost impervious to Mineral Spirits. For example - the brush I used for this Top Coat I could store in a small can of Mineral Spirits and it would remain soft and usable again. But for brushes used for original POR-15 they just hardened rock solid in the same container. I love POR-15 but be aware that this is a different paint.

Works as expected.

This does not cover with one coat. Each coat takes longer than 24 hours to dry. When applying with a brush, I find that it runs easily. This is totally different than P-15 black. I thought it would be like the black with nice flow out, but it does not flow out and cover. I am disappointed.

I have been using por15 for years and I believe it is the best paint over rust encapsulation products on the market. Expensive but works and is worth the price. Highly recommend product and seller.

Maybe you’re reading this because you have the por15 base coat and realize it needs top coat. This stuff dries like tub glazing. I’d highly reccomend.
