Stan, I've got plenty of acrylic here. :D
yes possibly, i thought so too, but some time elapsed between polishing and turning it over.
I might resand and see how it goes, not confident though...

Yikes...
OK. Lets see if we cant nut this out.
First, did you sand right back to bare wood and reaaply the stain/ paint?
Second, what type of stain/ paint did you use?
There may be an incompatibility issue here.
hey DB, first it was the ink and wipe on poly, the wipe on poly was tinting yellow as it dried and i didnt like it.
rubbed it back to the ink, not bare timber. on the back just rubbed it back to timber and used an automotive primer, top coat black and clear, all acrylic, all the same brand, all good quality from an automotive paint seller.
tried sticking my fingernail into the top, in a spot that wont show - left a small cut in the surface easily, like it's still too soft. surely not, it's been a couple of months and the last few days have been hot, around 30...
resanded the back, came out ok, repolished, glossy, far from right, but it will come up ok. i'm concerned though it will still be "soft".
after turning it over, very minute signs of the towel affecting the top. this is a clean towel, with no chemical exposure. it's the paint cure i'm sure
sanded back to 2000

Stan to be honest the paint must be quite thick and not left long enough between coats. This is not a reaction with anything else as acrylic does not react like that. Cut the clear back to as thin as you dare and leave it for two weeks without polishing it. After a couple of weeks start with the fine cut and then polish.
I agree with Jrod's diagnosis.
From what you have said you did it right except perhaps went in a tad heavy handed... I am guilty of that one too :p
