neither you want a non yellowing conversion varnish or a 2k poly

Those are pretty vague parameters. Lacquer is a very old-school coating for cabinetry. If you are doing a white or light color, the oil base of the lacquer will make the paint start to turn yellow in a few years, and lacquer itself can be more or less a chipping risk depending on the brand. It appears Insl-X is the name applied to paint from several different sources. Can you provide more information? Usually for a lifetime warranty on cabinetry finishes, you need to be looking for a 2-part, post-catalyzed conversion varnish. The newer 2-part formulations are waterborne like from Milesi, Sayerlack, Renner, ICA, and Ilva and completely elminate the risk of yellowing over time due to the waterborne nature. If you find a cabinet builder who uses 2-part waterborne Milesi coatings, you have hit gold. The 2-part, post-catalyzed conversion varnishes that are oil-based but have anti-yellowing components added are a close runner-up. The 2-part includes a hardener that gets mixed in to the main paint right before spraying in the case of post-catalyzed and adds chip resistance, moisture resistance, and chemical resistance (there are lots of chemicals in the kitchen from food containing acids) that makes a lifetime warranty possible. With a one-part finish, you can plan to re-coat your cabinetry in about 7 to 10 years if the chipping and wear bothers you. A professional cabinetry sanding, prep, and recoating job runs on average about $7,000 for a medium-sized kitchen (8 to 12 cabinets). You might want to consider getting quotes from some larger companies that do the 2-part conversion finishes in the factory.

Thanks for your insight! We’re planning a dark blue cabinet, and as far as the Insl-x, he said it’s a Benjamin Moore product. I’ll have to inquire further.

Glad to know that lacquer has a tendency to crack- that would be terrible!

@Jen Lacquer primarily yellows and chips, which is different from cracking. OK, so if you are looking at Benjamin Moore's INSL-X Cabinet Coat, I believe this is a product that has oil in it but can be cleaned up with water. It supposedly dries down to an oil-based type finish but also has properties of acrylic. It is a one-part finish. It is easy for the painter, not so much for the client who has to live with it according to some reviews. Long story short, you could end up with serious defects early on. I have read numerous reviews of longevity problems. To reiterate, your best cabinet finish is a 2-part post-catalyzed conversion varnish or a 2-part waterborne from a company like Milesi. The thread below is a good starting point for your research. The original poster is speaking of the Benjamin Moore INSL-X Cabinet Coat, just to clarify. There are other threads on this if you want to research further and look at other reviews at various websites outside of Houzz as well.

Thank you so much, @Aglitter !

I wanted to update this post and say that since my previous comments, I've done more research on coatings for the DIY market, and INSL-X actually stacks up fairly well, and I'm even planning on using it on some trim work I am doing. It still isn't a coating that would be ideal for cabinetry that sees heavier use than trim work. Some people have complained that INSL-X Cabinet Coat has a propensity to gum up around the handles where skin oil contacts the finish, but that problem is also seen with Sherwin William's ProClassic or Benjamin Moore's Advance. Also, people have noted that the semi-gloss in INSL-X is more durable than the satin. Also be aware that some pro painters may have a habit of thinning paint or adding other things to it for application purposes that could decrease the durability. Envirolak out of Canada is supposedly an up-and-coming coatings supplier that caters to the DIY market and has excellent products that would be comparable to INSL-X or possibly better. Milesi coatings are also great, a coatings company out of Italy, but their products can be hard to find in North America for the DIY market. There is a Facebook group where one of the members sells Milesi to anyone in the United States, here: https://www.facebook.com/groups/diycabinetrefinishing

That crackiswack Lucky is not an authorized seller and is getting his scam yanked by the actual company authorized distributors. Milesi is very easy to find, if you look at the authorized distributor list. If you want smaller quantities more suited to DIY, look at InspiredbyU. Actually authorized. The whole system, from primers to glazes. For bigger quantities, DC Clark at Clark Deco, or Harvey Zook at Timberlane Finishes ship everywhere. https://www.shopinspiredbyu.com/
