Hello everybody, I am currently finishing a jewelry box. I am using Arm R Seal semi gloss urethane and am having problems with the walnut burl top looking like it should. The sides are not burl and took the finish very well. The top has many coats built up but I can not get rid of the streaking that I cause when I wipe it off. I have tried not wiping after I apply it but then it doesn't lay flat and it still looks bad to me. I have tried cutting it with mineral spirit at 4:1 and it looks a little better but not like it should. Would it be ok to put lacquer on top of the Arm R Seal ? I have read that you can and can't. The gloss would be ok with me if it is ok to do. Any help or comments are appreciated as I don't want to sand the whole box down and use a different finish.
Thanks for reading .. Ron

Ron, I am not sure what is going on with the finish on your box. Part of the difficulty with streaking comes from your wiping it off. The Arm-R-Seal is designed to be wiped on and then left to form a protective film. Wiping it off will produce streaking since this is not a penetrating oil like boiled linseed oil. It is a designed to form a surface film that will protect the wood from incidental damage.

You can put lacquer over the urethane but you need to let it cure out before doing so. I would recommend at least at least 72 hours and to as long as possibly a week, depending on the ambient temperature to allow the urethane to fully polymerize. Once this occurs it will be unaffected by any solvents in the lacquer.

As a suggestion have you given any thought to using shellac?

Hi Scott, I gave a coat of shellac a try but it didn't want to lay flat at all. The finish now is so built up that it is like glass and the shellac just wanted to dry instantly and it looked really bad.

It looks good if I don't wipe it after I put the arm r seal on, but I have brush marks. Ive tried a sponge brush and a wiping rag and it still shows marks from dragging. I,m thinking that I may do a couple coats of lacquer after it dries. This way when I'm done it will be flat with a gloss, no wipe marks and no streaks.

Thank you very much for taking the time to help me Scott. Ron

I know that some burls are very absorbent and it takes TONS of coats before it will start to build up on the surface. I am not sure if this is the same problem you are having or not. But I know you can put lacquer on top of just about anything as long as it has had sufficient time to cure.
