You may need to add more super glue to the tray if the initial glue has dried up. P (also include N and R) are designations regarding the filters "oil" compatibility. Lower viscosity glues spread quickly across the surface of the foil boat and are vaporized more easily than thicker glues that tend to mound. You cannot paste images directly. Low viscosity glues are quicker to vaporize and can thus reduce processing time, but some will thicken with age and thus necessitate a longer exposure time. Ridge detail on nonporous surfaces, either latent or visible, can be exposed to cyanoacrylate (Superglue) fumes. 9 years ago Despite the fact that Starbond EM-02 Super Glue Kit is the most expensive product on this list, it's one of the best value products.
