There are a lot of glues on the market. Any glue has a limited array of substrates it can be used on. Some substrates seem easy to identify (leather, wood), but are actually not (leather usually does not include teflon-treated leather, very common currently) some require more intimate knowledge of the
thing you want to glue (PET vs PE).
I do not propose a universal glue, but rather a little stick that accompanies the glue, or can be bought separately for a reasonable price, that is composed of a glue that resembles the main glue in substrate specificity, but is different in the time it needs to set: e.g. instantly, at room temperature. It need not be resistant to water, uv, time, bending, squirrels or any other hardship the main glue has to endure during its life, because it is simply a testing stick. If it sticks to the substrate, the main glue (after its appropriate setting time) will too.
No more waiting for the expensive two component glue to set at a perfect 175°C, to later notice it would have worked, if only the substrate had not contained [insert weird substance].

I thought this would be a website like www.willitblend.com that's less exciting to watch but more useful. |

Problem is, though, that it will be hard to make a "quick and
cheap" version of the glue that have the same adhesive
properties. Only a two-part epoxy is going to behave like a
two-part epoxy on all possible surfaces. |
