Hi to all
I thought I had read on here that to solve fogging problems caused by Glue you should use Pure Amonia. I hunted today and couldnt see it. I and my felow modelers would be interested to know if any other modeler had done this? And was it a success? Apparently you apply it with Q Tips and if paint and or Klear has been applied before glueing then it doesnt affect the applications. Would be interested to know if any of you guys had any knowledge of this?

Why not just use glue that doesn't cause clear parts to fog?

I apply Formula 560 canopy glue to lenses and kit glass to apply, no fogging, dries very strong and clear. Cleans up with water if you have an "oops" before it dries. Superglue is pretty harsh stuff for delicate parts like clear lenses and glass. Micro Krystal Klear is basically the same stuff, and some people use watch crystal cement or a Testors cement made for clear parts. 5 minute epoxy is okay but yellows with age.

Every time I had glass fog from superglue fumes it was just a powdery residue that easily wiped or polished away, as long as it wasn't sealed in place where you couldn't reach it.

im not sure about the ammonia part but i always coat clear plastic with future floor wax (i think its called "Kleer" in other countries). then you can super glue it to your hearts content without fogging. but like someone else said i would now just use elmers white glue slightly diluted with water or that micro clear glue which to me seems the same as elmers but more expensive.

ammonia removes future floor wax so maybe what was meant was to coat the windshield with future and then use ammonia to secure it by melting the future where it contacts the part to be glued to.

but the future floor wax will also do a good job of hiding any scratches and marks on the windshield and also does a great job of holding small parts like headlight lenses or even photoetch stuff.

well you learn something new every day. I must admit I havent heard of the products you speak of. Formula 560 etc. it may only be available in the U.S. The other products are universal and I must admit I would not think of using that on Models. Thanks for that guys I will suggest it to my modeling buddies and see if I cant get a hold of that Formula 560 as it seems to be specific to that job.

As I said earlier great help thanks especially to the link supplied by bill geary. It was passed on to one of my modeling buddies today. He had problems with a kit he had spent ages (5 months) on. On applying the canopy( he is in to military avation) it fogged.Unfortunatly anger got the better of him and in 30 seconds his kit was a pile of black and yellow bits. You should have seen his face when he read the solutions you guys provided he is away to the hardware store to get some household ammonia as he has a project in his loft that had an oops! Many years ago but he is going to give it a try.

A light coating of Bare Metal polish of Tamiya rubbing compound works just fine and cleans up any fine scratches.

even after the canopy fogged, if he had applied future over the fogging it would have disappeared and he wouldnt have ended up with a pile of parts.

again, ammonia only REMOVES future, it doesnt in and of itself glue stuff together nor prevent fogging that i know of.

I was helping my son build a model and we managed to fog one of the windows by using superglue to glue the window unit to the roof, I just polished the tamiya polish, I would imagine that any polish would do the same
