APPLYING POR-15 TO SEASONED OR RUSTED METAL: First, wire brush loose rust and scale. Then remove any grease or oil with POR-15 MARINE=CLEAN and prep with POR-15 METAL-READY. DO NOT USE SOLVENT- BASED CLEANERS.
PRIMING OVER POR-15: Use POR-15 Tie-Coat Primer after POR-15 is dry, following directions on can. Tie-Coat Primer may be sprayed or brushed in multiple coats if desired. Sands to a perfect finish.
CHROME MOULDING CLIPS can scratch a new paint job when they are pushed through the body. POR-15, even if scratched off, will only rust where it's removed, so rust won't travel upward to ruin that new paint job. Coat around holes and under chrome before you prime and paint.
ROOF DRIP RAILS are a place where rust begins early. Put on a coat of POR-15 and let dry. Then apply a second coat, wait for it to dry, then apply a coat of POR-15Tie-Coat Primer and topcoat as desired.
STAINLESS STEEL TRIM PIECES that push down around the windshield... if they won't stay down, put some POR-15 in the channel and brace it with wood strips overnight. Regarding windshields, with the rubber removed, put a coat of POR-15 around the body where the rubber rests; this is a high humidity area and should be sealed with POR-15. POR-15 INSIDE REAR EXHAUSTS will stop rust where it starts.
LOWER COWL SECTIONS, ROCKER PANELS, LOWER PORTION OF FENDERS AND REAR QUARTERS, INSIDE DOORS are other good places to coat with POR-15.
RUSTED OUT PINHOLES: Put a piece of tape behind the larger pinholes, then paint. When the paint dries, pull the tape off and paint the back side as well. POR-15 can be used to seal gas tanks, also, and POR-15 PUTTY will take care of larger holes.
OLD CARDBOARD INTERIOR PIECES AND MOLDED VINYL VISORS can be coated with POR-15 and then painted over with vinyl dye.
Reminder: POR-15 SHOULD BE STIRRED, not shaken, each time you use it.
