Three good ones:
Duck Power Tape £4:99 big roll - very sticky, very hardwearing
Sellotape all weather outdoor tape £4.00 ish in a clear/greenish colour - ditto
Carbon fibre by MOTRAX from motorbike shops
A4 sheet £9.95 in real carbon, carbon/kevlar. also make strips & dots (10 of each) for £6.00
Both are better quality than Pace ones, and you get more for your money. they have REALLY strong adhesive (maybe a bit too sticky) although it can be a bit prone to curling off if put on a tightly curved surface, as do the pace ones.
