   Steve, often a subsequent coat or two, perhaps ragged on, will hide the 'witness' marks where you sanded through. You've come across one of the main pain in the erse characteristics of this particular finishing product. The other one is the tendency of the stuff to peel off in sheets a couple of years after application. Polyurethane varnish doesn't really want to adhere to itself, hence the need to sand between coats so as to provide a key between layers. Slainte, RJ.

   Do I work really hard, or do I hardly really work?

   Thanks for your response Sgian,

   I now see why many hesitate to use poly for this type of application. I have found that I can put a few drops on and wet sand, feathering back into the rest of the field. There is still tell-tale rings, at least that can be seen in more glossy sheens.

   I think I will try wiping on a new thin layer or two to cover these. I am wondering do I really need to sand down to 220 to provide a good key for the wipe-on, can I use 600 or 800? The problem is that the wipe-on film is so thin that the scratch lines are relatively visible. I am afraid of having to sand and level again, thus risking burning through again. I'd like to be able to just rub it to a finished sheen.

   Thanks, Steve

   Hi, I haver had the same thing occur, try sanding between coats w/ water and pumice  (i thing that is right, the white one, not Rottenstone thats the black 1?? and the very fine 1??) This will minimize sand thru Hope that helps

   Thanks Dave,

   Thats something I hadn't even thought of in regard to polyurethane.

   Steve,

   I have had good luck using scotch-bright finishing pads between coats. These do not leave organized scratches and remove very little of the finish.
