"Heat" is NOT what will cause vinyl film to come away cleanly WITH the adhesive. Get it good and hot and you'll remove the film.....most of the time, but the entire system? Nope. It's not just heat that will release it together.....It's the temperature difference between the film/adhesive and the substrata. SO....Ideal conditions: Very cold substrata Quickly applied heat to the FILM surface.
We teach novices who are right handed to heat the tip of a stripe or letter, lift the edge of the film (the adhesive MIGHT stick on the first couple of inches) and aim the heat gun to the right at a 45 Degree angle and strip from left to right, moving the heat gun slightly ahead of your left hand and the film. If your left hand stops.......direct the heat gun away from the surface.
Do not allow the heatgun to dwell on the film. If you heat up the substrate you WILL get delamnination between the film and the adhesive. Too little heat....film breaks. Too much heat......delamination. This is a delicate balance of temperatures and pulling the film. This method is the norm. You will always have situations where almost nothing works......but all things being equal.....cold substrate......quickly applied heat to the surface works for THIS method of removal.
Keep your eyes on your OWN papers! No cheating!

I don't know bout that ! Try heating up the whole area with large "heat lamps" from the body shop. This is the fastest method I'v seen, if there is any adhesive left,a little Rapid Remover makes short work of it ! Roger

Tell ya what guys, Let's have a showdown! Here in a few weeks I have to strip and re-letter 38 cars, both of you show up here use your own methods, and the one who gets the most vehicles stripped wins the rights of saying their method of removal "rules"!!! (a guy has to atleast dream!)

when pulling the vinyl off, pull it at a 30 to 40 degree angle. Its harder than pulling up at 90 degrees or 130 degrees, but almost every bit of glue stays attached to the vinyl.
I'm not gonna get in on the contest between Roger and Pierre.

Last October I got to strip a semi trailer before applying new graphics to it, and I did both sides in a half hour and didnt have to deal with any adhesive being left behind..
In this case I didnt *have* to use heat, I had no choice in the matter as it was 115 degrees that day with powerful Arizona sunshine.
The vinyl virtually melted off the side of the trailer, it was so easy to pull up.
I was expecting to have a huge mess of adhesive to clean up as well (had my RapidRemover handy) but there just want any to clean off. =)

Using a heat gun on a pinstripe is fine, using a heat gun on a large area of copy or large logo is going to take you some time. As for torches, I'v only used them when cutting or brazing or shrinking metal. What happens to the side of that alum. truck or trailer when you get one spot a little too hot ? Maybe ends up looking like the Atlantic ocean on a windy day ? Roger

Roger, let's not argue about this. Different methods work for folks in different climates better than others. Please don't tell me about large webs of film. We're the one's all of the local trucking companys come to for large format removal. We use a variety of methods for different films. I was with Arlon from day one. My kids grew up in the industry and both of them are very fast and very proficient at large web removals. There are times that your method may be the right one, but don't make it an absolute. There are none. Smile, Roger.....we're on the same team!

Roger......I should have added that both of us need to remove as much film as quickly as possible to make room for the newer, more expensive decals that will also soon need to be removed!

Another factor left out is what brand vinyl your removing? Controltac? life is good. 3mil vinyl that's been on for 5 years? life sucks. Avery makes a new line that is supposedly guaranteed not to leave adhesive.
