It is chemically resistant against a myriad of compounds and practically all household chemicals. G.R.P. is rated in the trade literature as having 唯Good乾 to 唯Excellent乾 resistance to acid attack and 唯Fair乾 to 唯Good乾 against alkali attack.

Bacterial and fungi growth are not supported by G.R.P. Planters., hence, it won't mildew, rot, nor, even degrade in their presence. Blows and bumps that would permanently dent or wrinkle sheet metal or concrete, leave the G.R.P. unscratched. Cost effectiveness of G.R.P. when compared to other planters, more conventional materials will vary from project to project. In most cases G.R.P. has proven to be a very cost-effective material.
