Never had success with this as the hymer has a pimple effect bodyfenwicks black streak remover
I use Fenwicks Caravan Cleaner as recommended in the Fenwicks YouTube series starting at this video. The big thing is to ensure that window frames, door handles, etc. are all cleaned until they no longer streak. I don't use Bobby Dazzler as I've found a better product (Greased Lightning Showroom Shine) to polish the (now clean) bodywork. It needs doing once a year (takes me all day) and then I go over a bit with Greased Lightning each time I have some spare time when camping (ten minutes or so per section). That said, I store the van where I don't have a water supply, so I've got to use a method that is economical with water. HTH, GeoffNever had success with this as the hymer has a pimple effect body
That's the one I was thinking ofDoesn't look to me as if either of them worked

You should have seen it BEFORE I fixed the streaks
An option for dealing with Black Bumpers going grey and horrible is the heat gunThe aerosol cans " bumper shine" ( or whatever) from the pound shop worked better that the more expensive " back to black" and others for removing those horrible light grey streaks from the black/ grey bumpers. Got to keep doing them mind but they do give good results. ( don't ask how much they cost eh?).
