quality tintz

The vertical felt guides. Like this except all the way up, I just slapped a little on for the example 
 

Any vehicle that has felt, and not plain rubber, needs tape to contain the felt particles that will fly off during install.  
 
Edit — this needs to be done before any water EVER hits the vehicle.   This is important.  

and you better pray that they don't love their armour all that makes life a nightmare.

I used to tint a four door for two crack rocks bout 40.00 just kidding started on my own then did family and friends just had them buy the tint at parts store...met my teacher a pro tinter and used real film with him wow what a difference glue and scratch coat were better hope this helps get good film and good tools!!!!

My tint teacher taught me if you ever touched the film like on a quarter glass or anything spray it off where you touched it before installing it

The seals pull on that one so you don't have to pull the whole panel. I do however pull the back to give myself more room. They ain't fun though
 

Umm  better hope it’s not a first generation.  That back glass is only for professionals.  

Yep, thats panel puller for sure. Tucking=you lose!

Pull the door panels or you're going to hate life. Those seals are deep and tight and you'll crease the shit out of your film if you try and two stage them.

Pulling straight in though, light will reflect off the bg, making near impossible to trim out dark film. Also, same effect makes it hard to see specs that need pressed out on sides.   Actually does come out cleaner peeling bg in rear of the garage versus peeling right where the door is open.  For the majority of rollups, i peel them off the bg and rear rollup, so the doors being open block a draft coming in some. 

technology has changed many new products now are thicker and easier to use and shrink.

get a 1.5 mil window film and get used to it I'd say. I learned with lulu AT and prefer the newer ATC the difference being an increase of .5 mil. Takes a little more heat/time to touch up but same product. Jet was cheap  turned purple in the box. 

First you cant control speed...it is what it is and will get quicker as your routine becomes more efficient. Just go for clean installs and dont mind wasting film, since its just more practice for you. 
 
For mobile, I only install in a garage and when the wind kicks up, i shut it while I stick it. You got to keep organized and have all your tools with you and back up tools in your vehicle. Oh yeah, always back vehicle in reverse for install. 

Try to wear an apron or have a rolling cart near you on the same side of the car.. Don't let tools you need be on opposite side. Install on one side at a time. Walking around adds up. 

Efficiency will come with experience, keep at and don't sacrifice quality for the sake of speed.

Car is totaled . Hope you have good insurance.

Trash bag is fine you just need heat and some sunlight. 
 
 

I'm going to give it shot, it should also probably reduce static, thanks for the input @TQtinting 

Thanks for the help guys. Im going to hit up some of my friends at work that have newer 4 door cars and see what happens. Ive tinted my car over 6 times now. Also tinted my wifes and sons car. I bought some SunTek. Super sweet tint.  Been picking up tools little by little and I have a good time tinting. Also Im a welder fabricator and work around 55 hours a week. 

Wouldnt cut it out even if someone asked. 

Just don't cut it out 😎

You make a good point. I could see that happening. I’ve always gotten super clean work this way. If it ever back fired on me I wouldn’t know it yet. But it makes sense. 

I started on junkyard car doors in my utility room at my house. Bought a 100ft roll of some cheap film did about 4 or 5 family cars. Watched more YouTube videos than I can think of and away I went. I won’t do anything I know I can’t tackle and I’ve prob got about 50 cars under my belt now. More than likely will attend a training course this coming summer. 
 
Just go for it but be smart. 

If you're "practicing" on other peoples cars you shouldn't charge them anything. You want them to pay for you to learn? Would you pay a mechanic to practice on your car? Also, not charging is a better motivation to get real good real quick so you can charge correctly when you're no longer practicing and know what you're doing.

If you go that route make sure to tell them this is practice and that in a year's time the price will not be the same. You don't want to get caught in a rut of people saying well you use to do it for this price. Also I wouldn't have them advertise it, just say hey if you've got a couple vehicles I could work on I'd be happy to. However don't bring your cousins husband's sister's ride up here.
