Hi all I have just finished making my own one-off carbon boot-lip spoiler (and carbon diffuser section beneath the rear bumper) and reading some earlier posts on here I understand that some people have used 3M VHB double sided tape to fix their spoilers in place and am considering doing the same with mine. (I do not want to start drilling holes in the boot lid). Apparently 3M VHB tape comes in various thicknesses, I am lead to believe, such as (approx.) 0.4mm, 0.6mm, 0.8mm, 1.1mm and 1.55mm and was wondering if any of you out there that have used this tape could recommend which thickness to go for? Any input would be much appreciated. Many thanks.
