I've got a customer looking to do an interior wall wrap on painted concrete block walls. I don't really get into wall wraps too often and am wondering your guys experiences with 3M IJ8624 and 3M LX480mC. I noticed that the IJ8624 is only rated for 6 months outdoor while the LX480mC is rated for 11 years outdoor. Do you guys use the IJ8624 for long-term interior graphics? I'm leaning towards using the LX480mC for that reason.... does it install the same as IJ8624? I was planning on purchasing the TA4 and using that for install or what do you guys find as the best tools / methods for installation.
