Example , pipe ? You can glue gray electric pipe to white water pipes and it works but it dont look good . White pipe carrying water to a water take should be buried but people just leave on the surface and the sun hits it releasing poly vinyl chloride into your water and you knowingly, or unknowingly ingest it and now your shooting blanks?
