Just watch where you fit these guys, the tape I'm providing is 3m stuff the first batch is a gell 0.2mm tape which I doubled up to 0.4mm as this will give it better adhesion to textured surfaces, rounded or curved surfaces is a no go with this tape ! But it sticks superbly to the ashtray and paint work or engine cover - be careful when fitting as it is pretty hard to remove especially when you have prepped the surface with the alcohol wipes !!
The second batch will go out with a slightly thicker 0.6mm 3m tape which will give better adhesion to textured or uneven surfaces !
On my sample plaque I tryed differant tapes and thicknesses and IMO anything at 1mm or over doesn't look very good as the
Gaps are too big - 0.4 - 0.6 are about perfect but I had to ditch the 0.4 mm in favor of the 0.6 as I had to double up the tape to achieve that thickness.
