I simply asked re EBT because it primarily lists it for the construction / building industry, whereas for example Sikaflex 221 Black is listed through Euro Car Parts as suitable for spoilers and wings /panels in the Automotive industry.
Incidentally, people who are passionate about their Omegas come on this site looking for helpful and cheerful advise, not rude or abrupt replies, which do nothing to encourage people to come back. A little explanation wouldn't go amiss - after all people wouldn't ask the questions if they knew the answers, yet those giving the responses may know the answers, but shouldn't expect people to grasp their understanding of the matter from short /abrupt replies.
Apologies - rant/gripe over.......
