bad spots appear after finish applied

[massey130]

I made a bowl on my lathe about 4"T or Deep (depending on your view) and 5"W or round. it is spalted Oak. as usual there were the punky spots that needed attention, but i worked it over and used up that little extra i left on in order to sand down.

it looked and felt right. i use CA glue as a bottom coat, then a deluxing creme wax and top coated with shella wax friction as the top coat.

i have used this formula for nearly a year with no problems and good results.
each layer went on nicely.

the next day, i found spots all around but concentrated in the punky areas where the grain looked like it lifted and are a few shades darker. now because of the heavy spalting, the bowl looks good from a customer point of view, but the bowl would be stunning if the spots had not appeared.

if the finish had "went bad" in patches as sometimes does, that is easily explained, but this spotting is making me scratch me head and say "HHhhmmm."

has anyone experienced something like this? I am not going to sand off and start over. it is going to market as is. it is a potpourri bowl with one of those pewter decorative tops. any comments or ideas are welcome. i have a lot of this wood and want it to come out nice first go round.

I have had things like this happen over the years and never really figured out jsut why. I write it off to moisture in the wood but who knows. I've never had anyone really know what caused it. This might be part of the fun working with a natural material brings to the party.

One thought i had and maybe i should have included this in my original post, but i am currently using the medium CA glue as i am out of Thin that i like to use as the base coat. it is cold in the shop and the medium takes longer to set. i don't know if different spots are taking the glue fast and the temperature is slowing down drying on the slicker areas and thus causeing the spotting.

this was an after thought. While i don't like sweating in the shop, i would rather that than shivering cold fingers and slow drying glue.

eh?
