Floor Pans, Inside & Out???

Thanks for the kind words.

You can use RustSeal alone on the underside of the floor, or apply an undercoating over the RustSeal. That way you'd have the rust protection and some sound deadening and/or heat insulation. There are a couple of products (Lizardskin & Second Skin) out now that are water-based that can be applied over RustSeal.

Figure a kit will cover approx. 50 square feet with two coat protection. Be best to just measure the area(s) you wish to cover. There is plenty of prep in the kit, you just may need to order an additional pint or quart of RustSeal.
