POR15 Top Coat in Chassis Black (was Chassis Coat Black)is a direct to metal coating designed to work incredibly well in all applications where there is a need to preserve substrates susceptible to corrosion
Chassis Coat Black paint has a smooth, satiny semi-gloss finish, and is probably more correct as original for underhood and chassis components for cars produced in the USA from the early 1950’s to today.
POR15 Top Coat can be applied directly to metal substrates, with no need for a primer or undercoat, and is formulated to form a robust barrier that sheds moisture to provide long lasting protection.
POR-15 Top Coat has excellent adhesion and when used over POR15 Rust Preventive Paint the products create a system works to provide a permanent barrier to corrosion.
- Non porous and will not crack, chip, or peel
- Amazing scratch and abrasion resistance
- Not sensitive to UV light
- Can be applied over POR-15 or other paints.

Stir contents well, then dispense a portion into a separate container and seal can at once, keeping lid and grooves clean to avoid permanently sealing can shut.
Do not paint directly out of can. Like all POR-15 coatings, this should always be stirred, never shaken.
Best Dispensing Method: Use coffee scoop or pouring spout.
o not put left-over paint back into can. Thin only with POR-15 Solvent, if necessary. Apply in thin, covering coats.
Surface to be coated should be dry and free of grease, oil, and other contaminants. Use POR15 Cleaner Degreaser (Marine Clean), diluted 1 part Cleaner Degreaser to 8 parts water to remove light contamination. Then rinse with water and allow to dry.
APPLYING CHASSISCOAT OVER OTHER PRIMERS
Repeat instructions above, then sand surface lightly with 240 grit sandpaper and wipe clean with dry tack cloth and paint.
TO PAINT OVER A CURED POR-15 SURFACE
Allow to cure for 30 Minutes at 68ºF (20ºC), or longer in cooler temperatures. Apply POR15 Top Coat as final finish. Depending on temperatures and humidity recoat at 3-12 hour intervals.
Spray Application: POR-15 Topcoat will need thinning using POR15 Solvent for most spray application 10-20%. Use 25-35 lbs.(172-240Kpa) pressure for normal semi-gloss.
Cleanup: Use POR-15 Solvent or lacquer thinner for cleanup, which must be done before the top coat dries; once dry it cannot be removed by solvent. POR15 Top Coat can take 3-4 days to reach maximum hardness or longer in temperatures below 55ºF 15ºC.
