I didn't grab a photo of the rims I was painting in their primed state, but I did make a YouTube short that shows it. They turned out as amazing as I expected, by the way. I simply followed the instructions on all 4 cans (primer, base, color, clear coat). Here's the link: https://youtube.com/shorts/FSWK-hENp9U?si=7E2K_P_3XsiGtoHc

Here in Arizona, the sun has faded out my yard art. My dragonflies lost nearly all the beautiful colors on their wings. Raven Super Colorshift has done a great job of showing off their details. I used the recommended primer in black-C2130. I loved the way it goes on and dries in 5 minutes. I used 3 coats. Then 3 coats of the Raven. Topping it off with High Gloss clear automotive paint. I love it!

I'm a DIY'er and have limited experience with paint. However, TSS and Alpha products made the job extremely easy and I couldn't be happier with the results. I used their entire system: gray primer/sealer, black basecoat, custom topcoat, and finally 2K clearcoat. Both the products AND cans were very high quality and included flow-adjustable nozzles, orientation control of the fan/pattern, and a wide fan pattern which makes it very easy to shoot paint like a pro! Thank you TSS!

Good morning. I bought this product from researching and recommendations that epoxy primers, especially on brand new unrusted and corroded steel. To have a long term sealed bond the preparation with a quality primer is critical to achieve long-term protection. My only complaint was the price. I don’t know why epoxy paints are so expensive but it’s the best product out there and will use again. Thanks.
