    Can anyone help me find a thixatropic CLEAR coating that will not run on vertical surfaces? Self leveling, high build clear coats are fine for horizontal surfaces, but what do you use when filling on verticals while allowing the wood surface to show through. Thixatropic additives like fumed silica reduce the clarity of clear resins. Is there another way of getting a thick clear coat not to sag?

    Almost any clear lacquer can do that.. just thin layer at once and a lot of them..

    Thin coats and many of them . . . It would be nice if you could apply a single coat and have the film thickness you desire, but there isn't any product I know of that offers this, so lots of thin coats . . .

    Yes I'm familiar with the onion skin method but was hoping there might be a one shot product. I was also hoping it was easily sandable, cheap, available, long shelf life etc. It's nice to dream. Thanks.

    There are clear PU fillers on the market which are relatively thick.

    The USA made Bristol Finish is a high build clear PU and has reasonable thixotropic qualities, but you have to be careful of damp nights, it can go milky quite easily (how would I know?)

    I too am a fan of Bristol, but on vertical and overhead surfaces, these heavy polyurethanes have difficulty. In any case, you'll still need several coats to build up sufficient film thickness.
