I've been reading the 'prep and respray' guide and it mentions that the 3M masking tape is the best one to use.
As a novice, how long could such a masking tape be left on before being removed without leaving a sticky residue? In the past I've heard of 24 hour masking tapes etc but I wanted to prepare and mask various areas of my mini so that I've got plenty to go at but wanted a masking tape that would be sticky enough to start with and also easy to remove a long while afterwards so that I can take my time when I come to spraying it.
Are there different grades? What if none of my local stockists actually sell it?
I hope the above makes sense

Cheers,
