valleyguy1 & jester7677- Hey, intersting topic (at least to me

). I wonder if the use of FK425 does/not matter, I got the feeling it did and quit using it, but I never did any sort of proper test.
I don`t think I`d use anything else though...there *is* some sort of synergy between FK425 and FK1000P; when my little tin of FK1000P dried out, I was advised to use FK425 to rehydrate it and it worked fine. I was advised to *NOT* use FK146 instead, different stuff in that...and that makes me think that just any ol` QD/RW might not be a good idea.
I`ve never had a bit of trouble with IUDJ not playing nice with FK1000P, but I don`t use `em at the same time for fear something might go haywire at the wrong moment.
But hey, OTOH...this discussion gets me thinking how when I rejuvenated FK1000P with the FK425, it worked so well that I became a fanboy for the stuff! Hmmm...adding lots of FK425 to the mix sure didn`t compromise anything that time!
One thing though, I`m always leery of comparing how the same stuff works on different vehicles...or even just different panels/surfaces. NOTHING lasts long on the rear bumpercover of my wife`s A8, but zero such issues on the identical panel of my S8. And I`ve had vehicles where nothing lasted long on the whole thing, never did figure it out.
