Gluing Windows
Posted by tbone on Friday, March 03, 2017 2:58 AM

Hello all. I have been buiding polystyrene model cars since 1970 (I was 9 then) but I have always struggled a bit with fitting windows into my models - even now at my old age. I am always very, very careful with gluing in the windows. But from time to time, occasionally I still screw up and get a bit of glue on my windows. I hate it when that happens - hurts the whole look of an otherwise good build - no matter how small the blemish is. I'm hoping some of you can give me some tips on installing windows without the danger of glue blemishes. Thanks.

I just got the double sided tape from Fastcap that was advertised and also tested. That seems like a great way to do windows. I'm a few days away from trying it out.

Johnt, please let us know how that tape works. I usually use Devcon 5-Minute Epoxy for glueing my window glass in as well as most of the glueing I do. The Devcon dries clear and makes for a tough bond.

I also get glue on windows, it doesn't seem to matter what technique is used , or how careful you are, it happens. I have recently tried cleaning up glue spots with headlight renew polishes, the end product turns out surprisingly well.

I will. It will be a few days to let the paint and decal dry before I can do the windows depending on the weather.

Try one of the UV light setting glues like "Laser Bond" or "Bondic".

You can tape or clamp your glass in place, run a bead of glue around the inside & then check to make sure you have no adhesive exposed before you zap it with the light.

If you find a spot of glue before you set it, you can just wipe it off.

Even after it's set you can still flick it off with a finger nail or the like.

Just be aware that these glues don't really have a super strong bond so you don't want to be pressing too hard on the glass after it is installed.

I just did the windshield on the 50 Ford pick up I'm doing. I pleased as punch with the Speedtape from fastcap. I used three small pieces for the windshield, and the hardest part was peeling the backing off the tape once it was on the windshield. The backing came off in two layers. When I started peeling only the top layer of the backing came off,like it would on old BMF. I made a second attempt to peel off the backing that was left, and it cane off pretty easy. Then it was just sticking the windshield to the cab. If I used the clear plastic glue I normally use I'd still be hold the windshield in waiting for the glue to set up. The tape is way neater and easyier to use. I'm a fan. I'm going to let it sit awhile and then clear my fingerprints off the glass.

It's hard to see, but I put a strip on the sun visor, in the middle of the top of the glass, and on the bottom of the glass.

It's advertised on page four of the Feb. issue. www.fastcap.com I noticed today that the bottom of the windshield had come loose so I took the window out and put a longer piece of tape on both the top and bottom. I'm hoping that this this will hold it better. It's so easy to do this way.

I use Glue Dots or Strips from Micheals Craft store ! Never a problem since they are reall sticky stretchy glue spots I touch it to the edge of the glass that will attach to the body strech it along the edge all around the glass using as many strips as need be found 2 usually work for me . You get one shot to get it in right once it touches the body it's stuck ! I add Reg model glue around the glass for extra hold !

I use 5 minute 2 part crystal clear epoxy and Tamiya tape..

I position the windshield where I want it, tape it in place with the narrowist of Tamiya tapes, and use a toothpick to add the glue in places I figured would work best.

It's 5 minute epoxy, but I usually wait about 30 minutes so it get's a great bite.

Hope this option helps Thumbs Up.

I love Mecum Auctions and Barrett/Jackson auctions and what would I do without Ebay.

Gator glue is a good option and for stubborn attachments to some a pillars, a small amount of CA glue works best.

Goofy62 suggested UV adhesive. I purchased a tube of Laser Bond and tried it. I have to say that this works incredibly well. Getting a bit of the UV adhesive on the area of the window that needs to be clear is not a problem as it is with polystyrene adhesive. Polystyrene adhesive will instantly "melt" a permanent blemish on the window, UV adhesive will not. You can simply wipe it off with no blemish. Goofy62 indicated that the bond might not be real strong, but I have found it to be quite strong. This was a good tip and I plan on using it from now on.

Funny that no one has mentioned just plain old Testors White Glue (the kind that they say also makes small windows). It dries clear, and washes off before it is completely dry, if you make a mistake. I use it for headlight lenses and even to attach tiny exterior pieces (door handles, etc.) to painted bodies.

The Testors clear parts cement is my 'go to' clear parts glue lately, though unless you clean up mistakes etc imediately, I find it is very difficult to remove. At least from acrylic paint.

Other glues I commonly use for windows and lenses are Elmers white glue, Future, clear enamel, and 5 minute epoxy.

A few years ago there was a Tip of the Month in SA where a reader had described a simple fixture that could be adapted to most car bodies that holds the winscreen in place for glueing. Ever since this thread first showed up I have been looking for that article but have not found it. If it shows up I will post it here. It's around here somewhere.

Gluing windows for me has been a problem since I started building. Desperately I sought other means to secure windows, with varying degrees of success.  Everything mentioned in the posts before me work, thank God. I use clear enamel (a friend uses clear acrylic lacquer) and now I found a cement called "Canopy Glue" used by military modelers which dries invisible. 

I use these two methods and choose which on fits best in the demands on that glass.

I do not have any stains on my clear glass like the old days.

After using some model airplane canopy glue ($) from my not-so-local hobby shop, I discovered that ALEENE'S original Tacky glue (cheap at Walmart) works exactly the same. It takes a bit of time to curem but it dries crystal clear I usually carefully, tack the window in place and when it's stable, go around the edges

Can't beat cheap that works just as well as anything more exoensive.
