I used thin, dime store CA. I rubbed the first coat on and then let it soak in/dry. You can see where it needs more, so go ahead and repeat without sanding. After 3 or 4 applications, you are just adding drops on individual pores. After several coats are dry, sand it just enough to blend in all the coats of CA. I tried not to take it to bare wood. I use 220, because that is always my final grit when spraying Fullerplast. After sanding the first time, you may have to touch up a spot or two. I started spraying after that. As when spraying any riser, a small amount of sanding was required between coats to finish the leveling. I was able to do this in one afternoon. Lot's better than the weeks it took last time, and a much better result.
