Midwest Winter Prep Follow-up Question: Top UPGP with 845 or FK1000P?

[GoCubsGo]

I have limited garage time for my fall/winter correction/prep which translates to about 36 hours after the correction is completed to apply my winter sealant. Initially I was going to go with FK1000P, but I can get 3 coats of UPGP in the time I can apply a single coat of FK1000P (12 hour cure between UPGP applications and 24 hour cure time between FK1000P applications).



I think I'm in good shape going with UPGP x 3, but was curious if I should consider topping the UPGP with a coat or two of 845 or FK1000P for added protection.



I ran a search, but couldn't find a solid answer.



Bottom line: Will 845 or FK1000P bond properly with UPGP or is it a waste of time/product?



NOTE: I've ran UPPP and UPGP on a few panels and like the results so my final polish step will be UPPP.

I think ( from search FK 1000P - I can be wrong ) 1000P have cure time 30 min so You can have 2coats of 1000P in 1hr. Don't top with 845,845 have lots of solvent and can remove 1-st coat. Again I can be wrong.

I have seen many more posts claiming fk1000p can be layerd after 30 mins to an hour than I have seen reporting it needs 24 hr cure time. I would give a coat of the UPGP followed next day by a coat of fk1000p. I wouldnt expect any problems with 1000p bonding over UPGP.
