1. Remove all loose material with wire brush and vacuum thoroughly.
2. Wash area with Engine Clean (Marine Clean) mixed with hot water, then rinse thoroughly.
3. Spray area to be restored with Metal-Ready and keep wet for 20-30 minutes; heavy rust removal will take longer. Rinse thoroughly with water and dry. It is very important that the metal is completely dry before applying POR-15 Rust Preventative Paint. Use a hair dryer to speed up dry time, then wait overnight to make sure no moisture remains in the pores of metal.
4. With scissors, cut pieces of Steel Reinforcing Fabric to sizes desired. Please note: if holes in floor pans exceed 1" in diameter, cover them from the underside with adhesive tape to avoid temporary sag. Adhesive tape can easily be removed afterward.
5. Apply a thin but covering coat of POR-15 Silver to a floor pan and place the pre-cut corresponding piece of Steel Reinforcing Fabric directly onto the wet surface. Now apply more paint until the fabric if fully impregnated, but not pudpuddled; too much paint at this time will result in bubbling, which is undesirable and counter-productive. Let dry 4-5 hours or overnight.
6. Use Epoxy Putty as needed to fill in low areas, welds, etc. Drying time for putty will vary according to ambient temperatures (surrounding area). Best time to apply putty is when POR-15 coating is dry to the touch but with a slight finger drag remaining.
7. Topcoat with one coat of Chassis Coat Black . Remove duct tape from underside of floor pan and apply two coats of POR-15 Rust Preventative Paint.
