prevention of 'torture' marks

hipcanuck · September 5, 2012

Im having some issues with complex curves/shapes. Im using 3M and when I encounter a hood with a up/down curve and a V trough in a 1 square foot area I cannot seem to avoid what I call torture marks, where pulling/pushing is leaving slight lines in the film.

I'm wondering if steam is the issue or perhaps a heat gun on low or hair dryer to soften the film a bit?

Perhaps I'm working the film too fast or pressing too hard with the hard card (wrapped in a cloth)?

Any help would b appreciated

3M is a very rigid film and very difficult to install. I stay away from it for that reason... oh and plus the orange peel and the fact it leaves a lot of adhesive on the paint when removed.

Use another film. Problem solved.

Now, when 3M introduces the new stuff at the SEMA show, we will see.

Sounds more like a technique issue than a material issue. I can't imagine a hard card would be a good overall tool for a ppf install. From what I have seen 3M uncoated Canadian film is a lot different that what is available in the states. Have you had formal training? If not I would look into that as it will be cheaper in the long run.

I resorted to the hard card when I found my black squeegee to be lacking. Ive since gone back to my squeegee and only get the odd mark thats only visible on black cars. I did get formal training, but it was only for a couple of days and unfortunately 90% of the training was on relatively flat hoods.

I was tempted to try resting a clean cloth soaked in very hot water on the nasty spot in question, but I havent got a car here I can try it on with a bit of scrap PPF.

I've only got about 80 cars under my belt so I'm still learning some of the finer points. Fortunately I work at a dealership so Im usually doing the same style car's which I guess is both a good and bad thing, repetition but very little variety.
