I just came back from a shop that specializes in boat and truck wraps for the fishing community and they have recently had a number of failures due to the use of unapproved cleaning chemicals. Be sure to follow the installer's cleaning recommendations to a 'T' to prevent any possible warranty rejections later on if issues arise just like window tint. Companies like 3M will request a sample of the problem wrap for analysis.

: Hot Sauce was just approved for use on all 3M wrap materials!
