What is the best adhesive for plastic on painted metal?

I have purchased a hollow, rubber-like plastic draft excluder that I want to use around the lip of a lidded box to keep the lid from rattling and, hopefully, keep out water. Although the draft excluder has a clip-like lip the rim of the box has no feature that allows that any purchase, thus I decided on adhesive.





At first I tried a thin superglue that I happened to have lying around but this did nothing more than leave a crystaline residue. Today I tried ';No More Nails'; in the hope that its purported ';instant grab'; would do the trick, however after several minutes constant pressure the stuff was still liquid and had had no apparent benefit.





So, I decided I'd ask here. What would be the best adhesive/glue for the (probably PVC, I think) plastic draft excluder and a painted metal box?What is the best adhesive for plastic on painted metal?
Hi, firstly No More Nails needs at least one of the surfaces it is adhering to to be porous and neither of yours are so that's why that did not work. There is one glue that sticks anything and everything. You can get 'Araldite' from B%26amp;Q and probably a few other DIY stores. Make sure you get the right one though as there a few. Ask in the store when you get there but as a guide you are looking for a blister pack that contains a syringe which is segregated into two parts. This is how the glue comes. Basically you need to mix it by hand with the implements supplied with it and then smear it over both surfaces. Do it quickly as it does part set quite quickly. Make sure you follow the instructions to the letter and leave the glue to cure properly for at least 12-24 hours. Good luck!!What is the best adhesive for plastic on painted metal?
Epoxy almost always works but make sure you get the type for the materials you are gluing. The epoxy will be labeled and will have different working and curing time depending on what you buy.





You could also try good old caulk. It works a lot better than most people think for a sealer. But it has a long set up time and cure time. But a good caulk maintains its seal with its flexibility during temperature changes.
Check with your nearest hardware store for 2 sided tape......They make some really strong 2 sided tape now a days......


Also you don't have to huff all that epoxy fumes also you don't have to worry about all the mess.....
