Re: [CBQ] Questions: Rosco CalColor 4330 Cyan 30 Film as Window Tint

["Jim's Junction trains28@bresnan.net [CBQ]" <CBQ@yahoogroups.com>]

      I use Testors Clear Parts Cement #3515 to glue the CalColor 4330 Cyan 30 to the inside of the car. It has good tack and dries clear and since the window tint is thin, it doesn't take much to hold it in place.

     Since I model in HO- I cut the window tint into 5/8" strips and then cut the long strips into smaller strips to cover 2 or 3 windows at a time. I run thin vertical beads of glue between the windows and then carefully lay the tint  in place. You don't want to slide the tint around or you might end up with glue showing on the window panes.

     Since the windows on O scale cars are much larger- I would recommend gluing strips of clear window material on the inside of the cars first. Then using the same procedure I use in HO, run thin vertical beads of glue between the windows on the clear material and then lay the tint on the inside of it. This will give the windows the strength needed to keep from distorting.

     I have done several Oriental Limited TCZ cars with the CalColor and when placed next to the other cars I have done using Proto Correct tint, you can't tell the difference. I first purchased several sheets of CalColor from a Photo supply outfit, but was disappointed when I received it, because the sheets were full of dents and dings. The tint is extremely hard, but because it is so thin, it dings quite easily. I ended up purchasing a 48" x 25' roll of the material at a reasonable price, which I cut off as needed. No dents or dings!

    I haven't tried tinting Dome windows with the CalColor so I don't have an answer for you on that, but it could probably be done with a little care and test fitting. Pikestuff makes Dome Window inserts for brass HO dome cars and that has worked well for me. I do have some Walthers HO Empire Builder dome cars and I have been seriously thinking about fitting CalColor tint to the inside of the existing clear dome glazing.

In a previous thread from 15-OCT-2015, Jim Olson stated that the following photo gel plastic film was equivalent in color to Railway Classics' blue-green tinted Proto Correct window tint plastic (which is no longer available):

Rosco CalColor #4330 Cyan 30 

Availability: 20" x 24" sheets   OR   48" x 25' roll

Material: either Polycarbonate (3-5 mil thickness) or Polyester (1.42, 2.0, or 2.5 mil thickness)

www.rosco.com

I ordered a couple of sheets to experiment with rom B&H Photo Supply (www.bhphotovideo.com).  I plan to use it as window tinting for the side windows of several 15" (60') & 18" (70') O-scale plated aluminum Zephyr cars from Lionel, K-Line, MTH, Weaver, & Williams.  

I have the following questions about this material:

1.  The Rosco spec sheet states that each CalColor film is made from either polycarbonate or polyester, depending on the specific color.  The spec sheet does not state the specific material (Polycarbonate or Polyester) for CalColor #4330 Cyan 30.  Does anyone know which material it is made of ?

2.  What brands & types of glue are compatible & effective with CalColor #4330 Cyan 30 ?  I will be gluing it to the inside of the aluminum car shells and also to the model's frosted plastic silhouette window strips.  Does clear Canopy glue work with this material ?  

3. Jim Olson had previously stated that this CalColor #4330 Cyan 30 material is more flimsy than the Proto Correct plastic.  Is it possible to make a laminate "sandwich" of the Cal Color #4330 Cyan 30 between two sheets of clear hobby plastic (in order to create a less flimsy & more rigid material) ?  

4.  Is the material a good or poor choice for tinting the vista dome windows ?  

5.  Are there better methods than glue for attachment of this material to the inside of aluminum car bodies ?  

6.  Any other suggestions for modeling with this material ?  

Thanks in advance for your responses.
