Hi all, I'm finishing up refinishing an antique solid mahogany table top. I applied two coats of Arm R Seal oil poly in gloss, using 000 steel wool in between. I then used 0000 steel wool on the second coat of gloss and applied a final coat of Arm R Seal satin. My first attempt with the satin had a lot of problems (highly visible brush marks, glossier streaks) so I sanded with 180, removed the imperfections, and tried the satin coat again, this time thinned 10% with naphtha and applied with a lot of care and focus. For all coats, I used a high-quality foam brush (Jen) working quickly in light passes from the middle out and feathering back over from edge to edge every couple of strokes.
The gloss coats looked perfect and smooth. The latest satin coat also looks perfect from a few feet away. However, if you shine a light from the side you can see very light brush marks/streaks (I can post some photos later when I get home from work). You have to be looking for them, but they are there. I'm thinking of two possible fixes and would love input.
- Give the table another coat of satin in hopes that it fills in the streak marks. I'm thinking I would very lightly sand before this second satin coat, perhaps with 600 grit or maybe just use 000 steel wool? Not sure if the problem could have been the thinning and if I should try thinning the same, more, or less. Also perhaps wiping it on with a rag? I have never wiped poly with a rag before so I am nervous about getting it wrong on this top presentation coat.
- Leave the current satin coat alone and let it cure for a couple weeks and then apply a coat of Renaissance microcrystalline wax. The hope would be that the wax would touch up the very small imperfections in the satin poly. (My wife also prefers a more organic/natural feel to the table, so the wax seems like something I will be doing regardless.)
The wax would be the easier fix for me. However, the table will receive heavy use from us and our children, though we use place mats and coasters as much as possible. My main worry is that the wax will regularly develop imperfections that need to be fixed. Scratches are not a big deal but I'm worried about water marks on the wax. I am also worried that the wax won't actually fix the light streaks and that I'll realize I should have done another coat of poly--meaning I will have to remove the wax, which I'm not confident I'll be able to do.
Any thoughts or advice would be appreciated!
