Durlaburban - That spray on magnet stuff sounds perfect, will it work on thermoformed acrylic - plastic?
I am trying to form a plastic sheet to the shape made by the balloon in the pic below.
tsuyosa - I have not tried it yet. if you are stretching the tint film I assume you are using the thicker peel and stick vinyl. I used some of that on the kid's windows of my vehicle. I have not seen the metallic type in this static cling variety.
I still want to try thermoforming the amber
colored plastic sheet, just need to create a form to mold to...any suggestions?
Below is a Q/A from Gila tint film manufacturer. It kinda shoots down any idea I may have had of applying tint film to plastic but it also explains in part d. why the tint film won't work in my balloon formed visor concept.
<blockquote>Q. Can I put window film on plexiglass?
a. Plexiglass, acrylic, and lexan are three non-glass materials used to make skylights, sidelights on front doors, storm door panes, and garage door windows. The advantage of these "plastic? materials is that they are more impact-resistant than glass. They are often more durable in certain window locations than glass.
b. Window film adhesive is not designed for these "plastic" windows. Changes in temperature cause natural expansion and contraction of both plexiglass and window film. The plexiglass and the film expand and contract at different rates, which causes the film to buckle and lift off the glass.
c. If you want to reflect more heat, you may cut a piece of Heat Control film to the size and shape of the window. Leave the clear liner on the film, and mount the outside of the curl of the film onto the glass after you put a ¼" border of double-sided tape around the inside perimeter of the window.
d. Do not try to apply film to compound-curved or domed skylights. Window film will not stretch to conform to these 3-D surfaces; but it can crease, pucker, and wrinkle badly if you try to force it to fit. </blockquote>
I just had a new thought on how to get a sagging sheet of soft hot plastic to form to my balloon formed visor ....
