In theory I'm off on holiday in a couple of weeks. As I'll be travelling through several European countries, and police and border staff might be a little sensitive at the moment, I figure I should get some kind of GB sticker. I've got 4Dot plates, so there's no room for the panel on the left, but this does mean there's a load of space to the left. I'm thinking that I use a removable tape to stick my small magnetic GB on. The question is, which tape? I want to be able to remove it, and there be no trace it was ever there. Quite happy to use solvents / clay bar / whatever to do the removal. Inside the back window isn't a good option as it won't be visible with the roof down.
