Can the wrap be removed later?

Absolutely, the material is manufactured to be removed. The wrap is actually applied to the vehicle using pressure-sensitive adhesives. Each vinyl comes with a 4 year easy take off period which means when you remove it 90% of the adhesive comes off with it. Although the wrap will not come off by itself, it can be easily removed. The removal process is very short and any remaining adhesive residue is easily removed with all natural adhesive removers. The material we use has an “easy take off period” of 4 years.
