Investing in "EcoPro Products" Protection

We have purchased a new small TT. The dealer just called and asked if we want them to do the EcoPro Products protection. There is an exterior shield that protects painted surfaces from damage caused by road debris, stone chips, insects, etc. and a microbrepelent used to prevent minor tears, damage, stains on drapes, carpet, cargo areas and ventilation systems. The cost of this is $1,000. The guarantee is for 10 years and we have kept RV's that long. We have a car we bought used that had a similar protection done and now it is peeling and spotting.

Our RV is stored inside and kept clean. Has anyone done this? Would you recommend it. Thanks!
