There are two popular methods for installing window tint: 2 stage and bottom loading. In this post I will talk about the age old question which is better 2 change or bottom loading. And you decide which one is right for you.
The 2 Stage Method
The 2 stage method is a process where the window tint installer does not take apart the door panel on the vehicle at all. Instead, the installer heat shrinks the tint to mold to the curve of the glass. The installer then puts the tint on the top section of the window with the window being down about 1-2 inches from the top gasket. This is the first stage. The installer squeegees the tints and takes out the soapy water with a squeegee. Then, the installer rolls the window up and installs the lower section of the tint. This is the second stage, hence the term 2 stage.

The benefit of the 2 stage method is that it does not require the installer to take anything apart. However, it requires a methodical approach, and the installer must have a process in place when installing. If one step is missed, the installation can be messed up because the installer is out of sequence. The 2 stage method requires constant repetition and technique to master, like any new skill.
The Bottom Loading Method
The bottom loading method is a process where the installer removes the door seal or the entire door panel. The installer does not need to heat shrink the tint because the seal is out and allows the tint to lay flat, so this saves time on the install. After the window is thoroughly cleaned, the installer can install the window tint in one piece and slide it into place to fit the pattern of the window.
Similar to the 2 stage method, the installer squeegees the top section of the window, then rolls the window all the way up and pushes out all the soapy water with the squeegee. The benefit of bottom loading is that you can drop in the window tint without any obstructions like the seal (sweep). Any tight side gaskets can be easily bypassed because of all the room on the bottom of the seal, and the ability to press gently on the glass while sliding the window tint in.
The downside of bottom loading is the risk of breaking expensive door panels or scratching these panels. It's important to try both methods and see which way you like. Whichever method you choose, the more you do it, the better you get.
In my opinion, choosing the right method for installing window tint can make all the difference. The 2 stage method requires a methodical approach and constant repetition to master, but it does not require the installer to take anything apart. The bottom loading method is quicker and easier, but there is a risk of breaking expensive door panels or scratching these panels. Ultimately, it comes down to personal preference and experience. I am personally a bottom loader and comfortable taking apart $700,000 Rolls Royce to a Honda Civic. But there are some cars that I will not attempt to take apart like the 2020-2023 Mercedes Benz S Class because of the tights panels and if removed will never go back on the same.
