Is there a High Gloss Clear Varnish

Is there a clear high gloss varnish? I have some nice white lines and I would like to add a few finish coats of varnish without turning them yellow, repainting, or taping. I have seen Epifanes PU Speedcoat Varnish on Youtube but I don’t think it’s available in the US. Totalboat halcyon is clear and works well but its not a real rich gloss.

We use Petitt’s Ultra Clear and it really works.
If your stripes are white now, it won’t turn them to a varnish color.
Worth a try!
