Marks can be removed very carefully with t cut if washing won't shift them, try meths though before t cut. It will be time consuming though, hence the high estimate for the work. As pointed out caravan paintwork is very thin, panels are supplied pre painted before building so it must be some electrocoating process.
If a caravan has not been washed for some time, best method is spray any mould & black marks with mould remover, leave for a while, hose down caravan then wash with caravan cleaner such as Fenwicks following instructions & rinse with the rinse solution here
If any black marks remain then try meths & then t cut as final attempt.

We have a Protec and have had no problems whatsoever. But as with any cover the van has to be washed before putting the cover on to stop grit rubbing on the paintwork. It would be interesting to see some pictures of the damage.
Been looking how you pics on,cant seem to find how you do it.I have 2 of the marks in my pics.
Hello, just been googling black marks on caravans, and found this thread, we were wondering if any caravanners are still encountering these marks in 2017 from Pro Tec covers?
Any advice would be greatly received, as we are getting nowhere with Pro Tec
Thanks, yes we are not putting the cover back on again either, it's not even a year old yet, plus the 1st time we used the cover it did not leave these unsightly black marks..I would just like advise on how to get the black marks off, it's so frustrating.
Thanks again, the Paintseal application sounds a good idea, will look into that once these marks have gone
