I can only echo the view of the majority here, keep the ppf on.
Morgan originally used the 3i product, which is effective but quite thick.
There have been a number of developments and there is now competition my preference is for XPEL, it is thinner and most importantly it self repairs. The wide sills on the Plus 8 make it difficult to het in without scuffing the corner and I had the film replaced because the 3i product marks badly. the XPEL: has not marked in almost 2 years.
