Well, fiddled with this again today. Was NOT dry. The oil, even with friction polishing and heat when applying, doesn't polymerize with the CA glue. I try-buffed it off with a dry piece of paper towel, which left the top part of the pen glossy and shiny, and the bottom part dull and streaky. So seems, that the bottom half did not cure properly.
I sanded it back a bit, then added a few coats of just the normal (not thin) GB. Pure GB, no oil. Was fine on the top half, seemed to blend in with the bottom half (the fatter part, btw). So I quickly applied some accelerator, then applied a couple more coats, which seemed to produce a nice, hard CA finish.
Sanded that down, polished it up decently with Zona to the 1 micron grit. It still has a slight satin sheen to it, but it is now super clear. I don't think it has built up enough to actually fit the pen kit fittings (Cigar), so I would normally probably have to add more coats until it was thick enough. But, it did polish up with those pure CA finish coats. Since the pure oil (not a drying oil) doesn't bond properly with the glue, I would definitely NOT recommend this, even though I was able to salvage it.
All of these blanks had oil-based finish on them before (5 kits, 10 blanks top and bottom). So, I'm going to pick up some BLO and maybe some Danish oil, and see how those two work with the CA. Hoping that the accelerants in them will hasten the crosslinking process between glue and oil. I will say this...the oil+CA finish has a different feel to it. It feels almost more like rubber, and that in a way, makes it feel better? Classier, higher end? Maybe that is just the GluBoost, though...this is my first try with it, and I haven't used it pure yet, so I guess I'll see if this slightly rubbery, rich feel is normal for GB.
I will say, the clarity is amazing. I've used StickFast, Mercury, Mercury Flex, TiteBond, and...I forget the other. None have ever produced the clarity of GB, and that's been my big turnoff with CA so far...it always looked like plastic. The GB+WO shine line still has a very faint satin-like glow around it, but, away from the shine line its truly crystal clear, which is more like what I get from Pens Plus (but, better!) That's the kind of shine I like, so, this may work for my needs. I'm curious to see if this crystal clarity persists with the pure GB...
Another benefit with GluBoost is that I don't seem to be allergic to it. I got a faint whiff (I guess the organic vapor respirator filters just don't fully bond with and filter out CA fumes???), which with all the other CA glues I've used usually means I'm in for a bad couple/few days. I had a slight scratch in the back of my throat last night, and just a tiny bit of wheeze for a couple of hours, but that was it. I seem to be fine today, no lung issues, no breathing issues, nothing. So that is a HUGE plus for me...I've had some truly horrid long-term reactions to CA fumes in the past, so kudos to GluBoost for making a SAFE glue!
