Typical problems when wraping cars
« on: August 02, 2011, 04:20:14 PM »
1. Did you ever had to remove a wrap and parts of the clear coat came off? I had this some weeks ago... Since then all customers have to sign that they are responsible for this... I simply can't see if there are already damages in the finish or if the painter did a bad job!

2. Vinyl comes of at the edges. Sometimes that is the case. Of course we use hot air at the end of the wrap to fix the vinyl. Do you use a infrared thermometer to do that? Which temperature do you use? We just bought a thermometer and try to keep the temperature at 90° Celsius at the edges to fix the wrap.

3. Cutting on the finish. Everybody who knows how to do a good wrap, knows that we rarely cut on directly on the finish. But there are some spots on each car, where it has to be done. How do you prevent cutting into the finish? Do you use tape when cutting, or do you trust in your sure instict? We try to use tape as often as possible!

Any other problems you could think of?

Yes, If you wrap a vehicle that has been repainted then there is a good chance that the paint may pull up when removing the wrap. We only warranty wraps on OEM original paint jobs. You never know how a vehicle was repainted so there is no way to warranty that.


2. Vinyl comes of at the edges. Sometimes that is the case. Of course we use hot air at the end of the wrap to fix the vinyl. Do you use a infrared thermometer to do that? Which temperature do you use? We just bought a thermometer and try to keep the temperature at 90° Celsius at the edges to fix the wrap.

When you heat stretch vinyl it will inherently want to return back to its original state, which is a flat sheet. Areas like deep channels and edges of fenders, wheel wells etc will shrink back if left to do so. Best advice is to post heat all stretch areas. 3M recommends 200 degrees farenheight, not 190 not 195, 200. That will kill the memory in the vinyl and relax it in its new state. Areas like door handles and mirrors will shrink back immediately during post heating, for a perfect finish you will need to wrap those areas with excess vinyl, & post heat before trimming. Using primer will help alot.  Using a IR gun will ensure you hit 200.

Another issue with peeling up and premature failure is 'fingers' in the vinyl edges, especially in high damage areas under bumpers and fender areas. Always use heat to smooth out these areas and use edge sealer tape to seal any exposed areas which will be subject to water or underbody damage.

3. Cutting on the finish. Everybody who knows how to do a good wrap, knows that we rarely cut on directly on the finish. But there are some spots on each car, where it has to be done. How do you prevent cutting into the finish? Do you use tape when cutting, or do you trust in your sure instict? We try to use tape as often as possible!


This is a misnomer, all pro wrap companies know you WILL need to cut on the painted surface on a regular basis if you do custom designs. If you are unsure of your abilities then do NOT cut on a painted surface. There are knifeless systems available but they do not create a smooth cut line. Tape helps with alignment but the only way is practice and maintaining a consistently sharp blade edge. When you are cutting on paint ALWAYS snap a fresh blade so your hand learns the exact pressure needed to score the vinyl and not cut all the way thru.

Any other problems you could think of?

Yes, lack of patience. If you are instant pudding and want to bang out wraps in the shortest time possible you are in the wrong job. Vehicle wraps are a test of patience and skill. If you are the type of person that freaks out at the first sign of a problem then this is not for you. If you anger quickly or get stressed out, go dig ditches. Vehicle wraps are all about issues and learning to adapt & deal with them on the fly to create a quality finished product for the client. Its not a perfect science, things WILL go wrong and the people that are successful are the ones that are calm, relaxed and can adapt to situations at hand, you need the patience to approach each individual problem and deal with it, then continue on with the job no matter how long it takes.
