Ok, have to admit that I am one of these people that wash and polish the MH after every trip
So, after a good rain and all the dust and crap has been washed off the roof down the sides, it drys to leave the black lines.
So, what's the best way to get rid of them?
The van gas a good covering of polish on, but they still seem to be a little difficult to come off. Would a good coat of wax applied after polishing help?
The van does lean very slightly to one side as my driveway isn't quite level, so it's generally only one side that get the lines.
Any advice greatly appreciated.
Also, is it safe/advisable to stand on the roof?
I can reach the front roof light by standing on my porch (see above picture), but am a bit hesitant about stepping onto the actual roof.

Probably a better bet then that porch.

Best read your manual re standing on the roof - our's has a twelve and a half stone weight limit - that excludes one of us!

As landscaper says,, check in your handbook, My Autocruise Wentworth roof take all of my 16 stone but only up to the line where the low profile starts.

If you just have polish on then you have effectively got nothing on, polish just polishes, does not give any protection. You need to have wax as protection.
