Non-specialist question stemming from standing in front of a dizzying aisle of consumer adhesives... These differentiate themselves via meaningless superlatives like "serious", "extra" and "ultra". I just wanted to know suitability-for-different-materials and some quantitative measure of "stickiness" :)
Update: Could there be a consumer rating system for glue - based on existing professional testing standards? (Note a rating system doesn't have to be a single numeric measurement in scientific units so can include any scaling/grouping function and include material classfications etc)
