[Chevelle-List] POR-15

[Craig & Cerena Robertson]

I'm thinking of coating the undercarriage of the car with POR 15.  I notice that they have a degreaser cleaner, neutralizer, etc.  Does anyone know how necessary it is to use these other items, can they be replaced with anything else or will the POR-15 work with out them if I clean the undercarriage.  Thanks   Craig
