POR-15 Top Coat Paint, Direct to Metal Paint, Long-term Sheen and Color Retention, 16 Fluid Ounces, Gloss Black

POR-15 Top Coat, Glossy BlackI applied this on my aluminum toolbox. After all was said and done, it seems to be a durable finish and sticks strongly. $50 for a quart of Top Coat plus POR-15 Metal Prep for $30 is quite expensive, so it’s my hopes that it holds up for a long time. It was relatively easy to work with and dries to touch within 3 hours. I didn’t need thinner or a reducer, but if it was to be sprayed it would be needed and would help with cleanup.I didn’t utilize the original por-rust prevention product for this scenario as it seemed unnecessary and overkill considering por-15 says this top coat can used by itself and my metal is aluminum which Top Coat can be applied directly to without a primer.Here were my steps:1 - I grinded to the bare aluminum metal with a 4-1/2” grinder wire wheel2 degreased whole toolbox with commercial degreaser, medium solution mix, brushed on and left it on for 10 minutes, then washed off water3 applied por-15 metal prep, whole quart, in intervals with spray bottle over 30 minutes to keep it wet with the product. Washed off with water then dried4 rolled on por-15 Top Coat, 3 coats (4 on top). Rolling is doable, but a sprayer would work much for coverage for something like this as it’s difficult to roll into the diamond shapes to cover the tiny crevices. Waited about 2 hrs between coats.5 let cure for 24 hours (cures in 72), then installed since the weather is good

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.

Works as advertised.

After a recent trip to the beach, the roll cage on my truck starting to rust. This was deeply upsetting to me, because it was previously coated in truck bed liner, but age and salt started to seep their way in. Finding POR-15 Top Coat was like seeing a ray of light shining down from heaven, because it boasted a nice matte finish, and UV protection. That meant that I could apply only one coat and get the result that I was looking for.I did it right, cleaned, sanded, cleaned again, and then painted on a fairly thick layer (even though they say thin is best). I followed the advice of others and bought a turkey baster which I used to transfer the paint into a solo cup, painted from the solo cup, and then threw away the paint brush and solo cup that I used after each session.The paint was pretty thick (not runny) which was exactly what I was hoping for. I was very careful, and had very few spills or spatters. If you do get a drip and catch it quickly, then you can wipe it up clean. It coated the rust perfectly and left an incredible finish, far exceeding my expectations in that regard.One quart went a long way. First I painted my whole roll cage. Then I painted the side body of the truck (which was also previously coated in truck bed coating). Then I repainted the bumpers, then the under body of the entire front end of the truck. I still had just a little bit left over, so I repainted my propane burner (that I use for brewing).I feel that using a turkey baster, solo cup, disposable paintbrushes, and keeping rags handy is key to getting a good result with this product. I was also careful to make sure that the lid did not get any paint on it as I heard it would make it adhere solid. I will say that this stuff will form a film pretty quickly when left to sit on its own, so work efficiently.I'll also say that I've used regular POR-15, and I like the Top Coat MUCH better. The regular stuff is runny, shiny, takes forever to dry, and doesn't have UV protection. There's probably an advantage from a chemical composition standpoint to use the regular stuff, but if there isn't, Top Coat feels superior in every way.As you can tell, I'm very satisfied with this product. I haven't taken it to the beach yet, so I'll update this review if it doesn't prevent the rust, but I have high hopes that it will.

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.
