Thats brilliant.

Selling film using IR is misleading and picking one by it's IR performance is short changing oneself. Here's the technical facts, confusing as they can be, will lead to a more sensible decision when purchasing film products: (N)IR is only one piece of the pie (48+/-%) and in many cases it is a select wavelength or a range of multiple wavelengths that they publish, but almost always never represents the 'entire' near infrared spectrum from, 780nm to 2500nm. The best measurement for determining a film's final performance is to compare TSER's (total solar energy rejection), the higher, the better, or SHGC's (solar heat gain coefficient), the lower, the better. After this, you must now determine how much light you want coming in. Visible light accounts for 48+/-% of the total solar energy coming from the sun. Visible light converts to far-infrared same as near infrared (and UV), once absorbed into a surface and radiates off a surface as heat (that we sense). Far-infrared is heat, near infrared is not. The sun's solar energy is comprised of visible light, near infrared light and ultraviolet light (just under 2% of solar energy). All three contribute to unwanted heat. All I can add about Johnson Films is, they are one of a half dozen film makers in the marketplace today that date back to before 1980.

Hi Dano, thank you so much for your reply. Even just knowing the term silvering/champagining and that that is what it is is very helpful. I'll certainly implement your suggestions for the rest of the car. I really appreciate your time!

The top mark looks like a piece of dirt or a paint nib. The other marks closer to the edges look like "champaign". I would add more soap in your bottle and use an ounce of 70% alcohol, or less, in your mix to heat up the glue. Use a second bottle with warm water to flush 80% of the soap from the last inch or so away from the edge and squeegee. and rince the edge completely. Then paddle out the edges with the hard card. Dry it with a towel and paddle it again AFTER you look at it for excess water. Spray it with more warm water before you paddle a second time to lube the surface and not introduce more soap that might get under the edge. Dry it when finished to keep an eye on the glue while you work on the next panel. With the matte films you may need a little more arm pressure on your squeegee. I usually use the "dark yellow" from Interwest for most PPF with plenty of soapy water on the surface to lube the squeegee and not scratch the material. Now, if you don't want to do all that.... you can use the corner of a clear-max squeegee to massage most of that down over the next few days and make it 80% better where only you would know it's there.

Hi Dano, Thank you so much for the reply, I'll check out those applicator cards on Amazon as suggested. I have posted another photo that might show the marks I was talking about a bit more clearly. Admittedly I haven't tried warm to hot water, so I'll give that a go!

A guy randomly asked about this, R Vinyl tint. Anyone know anything about it. I'd never heard of it. TIA

Thought I would add that the white and black, non ribbed specificly, seem to have the most slide action and usually won't scuff the film if the edge is fresh.

Is anyone familiar with Johnson Window Films? We are looking to install window tint on residential windows and are looking for a film that reflects as little as possible (while of course rejecting as much heat as possible). Their PD 75 EXT line has visible light reflectance of 8% and IR rejection of 56% and 79%. I just haven't seen any reviews online or anyone posting about it in this thread, so was just hoping to see some positive feedback, or any feedback really, before moving forward with it. Thanks all.

I can't see much in that pic but I would recommend using warm to hot-ish water to flush your edges when laying the film and using one of these lidco cards to finish your edgework before and after cutting. Since you're using a matte film you can probably get away with using a pen/poker to relieve the air. You can find both on amazon. Good luck.
