CA glue blooming?

Ok, so in a pinch I used some CA glue from my local R/C hobby shop.  I have no idea what brand it is because the bottle has be designed to be branded by the hobby shop.  Anyway as I am using it I am finding that  it is blooming unlike any other brand I have seen or used before.  Any suggestions on ways to remove it.  I am currently building several Walthers Conerstone kits.  At some point I will go and paint and weather these buildings but I was wondering if anyone had a quick hitter clean up meathod?

For my Cornerstone kits I used a plastic cement made by the german company Vollmer ( no, not Dave Vollmer), as for CA I use a needle or a hobby knive to bring it up on models or kits so the glue can "breathe" better, I also would recommend CA as a gel...this is how I do it...have fun

If by blooming you mean that the model's surface develops a "frosty" coating around the glued areas then I have seen this happen. Usually when the ambient humidity is high.

I love using CA glue on pretty much anything but I'm also a big fan of BSI (Bob Smith Industries) brand accelerator. Using it not only sets the CA very fast, it prevents it from frosting/blooming.

A quick swipe with a piece of old cotton t-shirt moistened with acetone should get rid of the frosty look (but it might also slightly melt the model's surface.  CA debonder (if it doesn't affect the model's plastic) will also get rid of the blooming.  But if you will paint the building anyway then I wouldn't worry about this - paint should cover it all up.

BTW, if the glue is branded by the hobby shop then it is likely from BSI (as I've seen that brand used by several local hobby shop with their stores name on it).  That is pretty good quality CA glue.

Peteski,

That is exactly what I am referring too when I say blooming.  This term must not be one model railroaders used but it is a common term in other hobbies I am or have been involved in over the years.  I did find a small website listing on the bottle that says BSI on it so good call on your part.  I like the bonding results but I have never had the issue to the degree I am seeing it on this particular kit.  The last few kits I had to be very particular with but could control it.  This time it is a little out of control.  I may need to back to Tower Hobbies and search for the stuff I have always used in the past.  I don't want to risk affecting the integrity of the plastic so I may just have to live with it until I detail and weather the entire scene.

Great information, thanks for the post and responses.  I recently discovered the joy of CA gel after years of only using the thin variety.

I haven't heard it called that, but I know what you mean. Never bothered me because I usually paint over it.
