I painted my laminated kitchen benchtops with Dulux renovation range a few years ago, but recently decided to use Dulux granite effect spray paint to spruce them up. Because the granite effect spray leaves a rough, textured finish, I then used White Knight Clear Bench Top Protective Coating to seal it before sanding it back to smooth with the new granite effect remaining in place. I'm now looking for advice on what I can use as a clear, gloss top coat to finish the job. The white knight protective coating paint didn't really seem to leave the finish that I'm looking for so I don't plan to use any more of it but now I'm looking for advice on the best product to use to get a nice clear, gloss top coat that will also be durable and non-yellowing.
