@poetry6666 the spray side of it is just an activator it won’t stain stick leave residual or anything, no need to mask or anything just apply the liquid part of it to just one side (either the body or plastic, rubber what ever is easiest) no need to over do it and no need to rush like with superglue ( until you use the spray) once the liquid is applied then spray the activator on the other surface and apply pressure, hold for 5 to 10 seconds an that’s it, no cleaning up needed (unless you over do the liquid, then just wipe of or wait for it to crystallise and brake it off, if you needed to jet wash after then I’m sure it would be fine but I’m sure officially it may say allow an hour to cure properly, but the stuff is amazing try it first on some test things, apply liquid one side spray the other apply pressure after 5 seconds your struggle to pull it back apart. It used to be the go to thing for kitchen fitters for mitres of cornice etc but then every trade realised they can use it and need it, there are now various brands out there some are still exspensive but that one will suffice and great for most things, and great product to have around the house
