Super Glue Fumes and fingerprints

[NOBLNG]

From watching Forensic Files I know that CA fumes can adhere to and highlight fingerprints. I clean my glue looper by burning off the dried CA, and I think that may be what happened here. The MR Hobby Premium clear coat is well dried and most fingerprints just wipe off…but not this one. I also clean the un-used CA out of my little glue well with a Q-tip and that instantly makes lots of fumes for some reason. And I am careful not to breath the fumes when doing this.

I use CA glue very sparingly for just this reason. It likes to mess up glossy and/or chrome surfaces.

You’re gonna have to sand that out.

CA and cotton don’t mix. Your cotton swab had an exothermic reaction to the glue and got hot creating that bad vapor. As a warning to all modelers, be careful with cleaning a large spill of CA with a cotton rag. The reaction will get nasty and possibly catch on fire.

Thank you, Rick for the information and warning concerning the CA and cotton.  All of us modelers need to take heed of the advise.

It will fog glass too. I use as little as possible and have little out on the bench. I put a dab into an old beer bottle cap (Miller works best, YMMV...) and toss the cap when I'm done. I'll use those little applicators or a toothpick.

I only use BSI Super Gold+. It does not fog.

Did you get the fingerprint fixed?

Yes I did Carl, thanks. A little Tamiya fine polishing compound did the trick.?
