  • I’ve bought this three times now.
Size: 1 Quart (Pack of 1) Style: Clear Coat
I’ve been using this product to clear coat an old steel desk. Overall, I’m pretty satisfied with it and I think it does what it does well, when used with an eye for a couple of pitfalls I have discovered. First, it promises a nice smooth coat without stroke marks when applied with a brush, which it does deliver. However, it delivers this by remaining very slightly fluid for at least ten minutes after application so that gravity pulls it down into a nice even surface. Therefore, it is very important to apply it only to horizontal surfaces. If you put it on the side of something vertical, you will get drips and ripples where it gradually slid down from where you meant it to be, even if it seems like it’ll stay put at the time of application. It won’t. Trust me. Second, the reason why so many people complain about this product in reviews. This product will start to dry out immediately upon opening and exposure to air. It doesn’t matter how well you close the can, it won’t last for very long. Once it’s open, the clock is ticking, and you must use as much as you want to hopefully within a week or two or at the very most probably a month. Perhaps it is possible to reseal it and have it last, I’m not an expert on these things, but nothing I have tried has been very effective. This is why I have purchased this product three times, I didn’t run out. When the can is resealed, something about the chemical interactions in the can cause pressure to build up. Eventually, the pressure will pop the top open, a bit of the product will ooze out of the crack, dry, and then seal the can shut. Two days ago I had closed the can, turned it upside down to try and prevent drying on top, and placed the can in a ziploc bag. Today when I pulled it out, some was leaking from the top, thankfully it had not dried yet. When I opened the top of the can, it made an audible ‘pop’ as I released the pressure, like opening a soda. Sometimes the cans seem to open themselves before they’re even shipped to you. Several other reviews complain they’re unable to open the can at all, and I suspect this is why. My second purchase was like this, which forced me to pry it open by brute force with a mini sledge and a very large flathead screwdriver, making resealing the can impossible. That one didn’t last long. The other two cans I bought were fine. Having said all that, you might think I don’t like this product. That’s not true. I do like it and I’m happy I bought it, though I’d rather have not needed to buy it three times. If you choose to buy this in spite of these caveats, I hope that you can learn from my mistakes and have a good experience. UPDATE 06/26/23: I have been having very good experiences with can #3 after the accidental eruption. I’m finding that it may keep in liquid form quite awhile longer than I thought, provided you keep it in the original can(I experimented with previous cans transferring to other types of containers and that did not go well at all.) I don’t believe storing it upside down was very helpful, and may have contributed to the leak. Moving forward, I really only have two strong suggestions for success with this product. 1. Apply on horizontal surfaces only. 2. Once you open the can, re-open the can every day if possible and every two days at minimum to allow for pressure release. I don’t know if eventually it’ll settle down and stop creating so much pressure, or if this is just how it is, but I’m down to maybe 1/3 of a can remaining and the idea that I might actually use all of this product before I somehow render it unusable is nothing short of a miracle. ... show more

Size: 1 Quart (Pack of 1) Style: Clear Coat
This is an amazing product, it took a bit longer to cure than explained but worth it. Glass appearance and hard.

  • Boat finish better but not great
Size: 1 Quart (Pack of 1) Style: Clear Coat
Product brightened up the dull finish as promised but got a lot of runs using foam brushes. Finish is very waves which was somewhat disappointing.

  • still off-gassing after more than 24 hours; would not recommend for interior projects
Size: 1 Quart (Pack of 1) Style: Clear Coat
I was trying to decide between this product and Rust Bullet Clear Shot and can't remember why I chose KBS over Rust Bullet. Both products have a noxious chemical odor and require an incredible degree of ventilation during and after application but I have used Rust Bullet numerous times around the house and it stops off-gassing after about 8-10 hours if not sooner. Unless you can leave your home for a couple of days I would not recommend using KBS DiamondFinish on anything inside a house that people are living in. My family is extremely upset with me and I still have one more coat to apply! We all have headaches and sore throats due to the KBS fumes even with an extraction fan running around the clock and windows open for cross ventilation. I don't even know if this product will survive the test of time but simply the fumes alone and the fact that it should not be used for indoor projects are enough of a reason for me to give it a low rating. I would recommend Rust Bullet Clear Shot as an alternative. I painted an outdoor bench with Clear Shot and it's holding up exceptionally well and looks great. update: I reduced my rating to one star since the KBS coating I applied is still releasing noxious fumes four days after application! I have never used a product that smells this bad for such a long time. I decided to not use KBS for any additional coats and will switch to Rust Bullet clear shot instead. However, the length of time it is taking the KBS coating to fully cure and stop smelling is seriously impeding the progress of my project. final update: called KBS repeatedly about my issues with their product and everyone I spoke to at the company was extremely knowledgable and kind to me. I am still confused why the KBS coating took so long to cure and stop smelling. Supposedly it cures faster with high humidity and I was using it during a rainy period in damp/humid San Francisco, CA. In the end, in order to speed up the curing process, I had to open windows to the outside on rainy days to bring in damp air as well as run a fan blowing air over the stairs I was painting. Even with all of this - the KBS continued to smell for an entire nine days after initial application! After that I had to just move ahead with the work and prep and coat the KBS with Rust Bullet Clear Shot. I would never recommend a coating that takes so long to cure and smells so noxious. My project was held up for well over a week due to my decision to use KBS. I switched to Clear Shot and the noxious fumes were gone within 5-8 hours after application and my project is finally moving forward. ... show more

  • Excellent product with amazing results
Size: 1 Gallon (Pack of 1) Style: Clear Coat
The media could not be loaded. I used this product to make my oxidized faded camper look new again. After trying multiple products and not seeing the results I wanted, I opted to use this product. The entire camper was stripped of wax and wet sanded to remove excess debris and imperfections, just before spraying the coating. I only did one coat on the sides and it looks great. The front and the back of the trailer have 3 coats and you can definitely tell the difference. For a 30 foot camper I used about 1.5 gallons. Also you can use XYLENE to thin this product for spraying- I thinned about 12.5% and sprayed using about 75 psi with a 1.4 tip. Makes the camper shinier than it was new. Thanks KBS! ... show more
