Hello, Would really appreciate if you could advise on the best topcoat for sealing a kitchen countertop. The Rust-oleum Worktop transformation kit has limited colours and so isn’t an option but I wondered if you sold a product that was the equivalent of the two-part protective top coat that is food safe and non-yellowing. I’m looking for something that is a simpler DIY application than Epoxy , though appreciate it will not be as durable. The kitchen counter top is Formica but I intend to paint and then apply a top coat. Many thanks J. Burke
