I've put these orange/black patches on both ways. I agree logically that you should take off the foil backing and stick them on - it's hard to do it the other way up as the plastic sheet is a sod to get off.
I am confused however, as cheap 'thicker' patches that you get in an Aldi style kit are nobbly on both sides, I imagine to help give a key for the glue.
The orange and black ones are very smooth on the foil side and nobbly on the outside (if it is correct to go foil side down). So why is this?
I've stuck them on both ways, and in my experience not had a problem either way - but I would have thought smooth side out would be better (same as the original tube) and nobbly side in would give a better key...
Just curious as to opinions?
