Filling in windows - method ?

[Puddington]

A few week ago in a thread some members here were talking about a method for filling in windows in passenger cars, the used an adhesive (I believe) and taped up the outside of the car, filled in the inside and when it dried had a good surface to work with. I've tried this with resin but they had another material... anyone remember who and what it was that was used and who was doing it ?

Thanks in advance !

I just used Bondo putty to fill in the windows on a coupler of streamliners. I forget the brand, but it worked great.

 Mike,I just did windows on a caboose yeaterday.I use Regular Scotch Tape over the window,because of the fine grain of the glue..Make sure you don't even get a fingerprint in the tape,it will show up! Put a flat piece of something over the tape,so it comes out flat.Lay the window side on a flat surface.THE best stuff to fill it in is JB Weld,the slow set,not JB quick. It takes forever to dry,and it just loves to flow out,and fill in holes perfectly..It should sit at least overnight before you remove the tape..

And we know this how ???

From doing castings..EVERYTHING shows up,if you can see it,it's in the mold..

Yes, don't put fingerprints on the tape.... don't.
One thing -- how do you remove the sticky adhesive left on the casting once you pull  the tape off?

For us N scalers who don't need 8 or 24 oz of epoxy for our jobs, there's a version called "J-B Mini" (Part # 8212-S) of a small double syringe mixer. You can carefully cut the tips off then use nails or the like to seal up the tips once you've got all you need. I've done two major multi-window shell plug jobs and still have half a tube left. And this is a .02 oz tube!

Confused.  Is this for creating window glass or just for filling in holes?

[LV LOU]

Filling in windows.If done right,there's only the tiniest amount of sanding needed just to make the surface blend in..

"One thing -- how do you remove the sticky adhesive left on the casting once you pull  the tape off?"

Using an alcohol pad or alcohol on a cotton ball should cut the adhesive once the filled area has set.

I am glad to know that the JB Weld flows smoothly... I am looking at filling some windows on MT heavyweights with the tape on the inside of the shell to create the look of a window whose sash frame has been replaced by a steel plate and this should work out quite well using it.

 Jerry,JB Weld actually has steel in it,so it's heavy.It will flow right out into an entire space,and flatten right out.Since it's so heavy,I actually like using it to cast my own personal diesel & steam shells.I have a PRR B6 tank loco that I used JB Weld to cast the tank .The thing weighs a TON,it will pull over 30 cars..One tghing I should throw in..Not really rocket science,this would happen filling in a window with this method no matter what you use for filler,but,if you're not careful,the corners will have bubbles.I usually let the JB flow in from one side to all four corners..
