Frequently Asked Questions About POR-15
MANY PRODUCTS CLAIM TO STOP RUST;
SOME ARE PAINTS, SOME ARE CONVERSION PRODUCTS, SOME ARE RUST TREATMENTS.
NONE SEEM TO REALLY STOP RUST PERMANENTLY.
Rust is caused by moisture coming in contact with metal, which causes a chemical action
called oxidation. All paints provide a measure of protection for a while, but since they are
eventually softened and weakened by moisture, it is only a matter of time before moisture
penetrates the painted surface and attacks the metal below. All of the so-called rust preventive
paints on the market (except POR-15) are weakened by exposure to moisture. POR-15 is
strengthened by exposure to moisture. Notice the hardness of the POR-15 coating. It doesn't chip,
crack, or peel like ordinary paints do, and its hardness will resist the wear and tear of every day life.
Rust conversion products claim to change the chemical nature of rust and convert it to a
more stable element that won't rust again. History of the failure of these products is
well documented; most simply does not work for more than a few months at best,
and then are subject to the same chipping and cracking that occurs with ordinary rust coatings.
Why does POR-15 PAINT STOP RUST PERMANENTLY ?
POR-15 works because it chemically bonds to rusted metal and forms a
rock- hard, non-porous coating that won't crack, chip, or peel. It keeps moisture
away from metal with a coating that is strengthened by continued exposure to
moisture.
IS IT BETTER TO BRUSH OR SPRAY POR-15?
Most people brush it on, but many spray also. Proper equipment and organic
vapor particulate respirators for solvents are essential for spraying.
HOW DO I THIN POR-15 IF I WANT TO SPRAY IT?
You should use only POR-15 Solvent for thinning. Keep lacquer thinner handy for clean-up.
Do not thin POR-15 more than 5%.
CAN I PAINT OVER POR-15 WITH OTHER PAINTS?
Absolutely. POR-15 will accept all paints, including lacquer-based paints. POR-15 Tie-Coat Primer
is the best prime coat to use before topcoating POR-15. Be sure to read thoroughly our
directions and tip sheets regarding topcoating before using POR-15.
CAN I USE BODY FILLER OR PUTTY WITH POR-15?
Yes. First paint both sides of the rusted area with POR-15;
then use body filler or putty as soon as the POR-15 is dry to the touch.
HOW LONG DOES IT TAKE POR-15 TO DRY?
That depends on the ambient humidity (surrounding area). The more humid the area, the faster
the dry time, which usually varies from 3 to 6 hours.
IS IT DANGEROUS TO GET POR-15 ON MY HANDS?
No, but if you do, remove it at once with solvent or lacquer thinner. If POR-15 dries on your skin,
nothing will take it off, and you will 'wear' it for 3 or 4 days until natural oils and flaking skin
remove it.
ARE THE POR-15 VAPORS DANGEROUS TO MY HEALTH?
Yes. That's why you must always paint in a well-ventilated area and keep your nose away from
the paint container. POR-15 is not dangerous if you follow our simple directions.
WHAT IS THE BEST SURFACE ON WHICH TO PAINT POR-15?
POR-15 likes rusted surfaces best. Seasoned metal and sandblasted metal are also good. POR-15
does not adhere well to smooth, shiny surfaces, but will adhere well to those surfaces with
the proper preparation.
WHAT IS THE 'PROPER PREPARATION'?
We make a product called 'Metal-Ready'. It's a rust remover that leaves a zinc phosphate
coating on base metal, the perfect preprimer for POR-15.
NOTE: New steel is coated with a protective oil finish at the mill. This finish must be removed
before using POR-15 or Metal-Ready. Clean metal first with POR-15 Marine-Clean,
then rinse with water and dry.
WHICH POR-15 (BLACK, SILVER, GRAY, CLEAR) SHOULD I USE?
Silver contains metal filler and should be used in badly rusted, pitted areas. It will fill in holes
better than black or clear. Black is generally used on frames, underside of fenders, etc.
because that is what matches the original color. Clear renders the smoothest finish
and is often used as a pre-primer on exterior surfaces; Gray is great on concrete floors,
bilges, storage areas, as well as steel.
MUST I PAINT OVER POR-15 TO MAKE IT LAST?
No, but POR-15 has an ultra-violet sensitivity and must be topcoated if continually exposed
to sunlight. Once topcoated, POR-15 will remain effective for many years.
WILL THE SUN DESTROY MY POR-15 COATING IF I DON'T TOPCOAT IT?
No, your POR-15 protection will remain, but the sun will change its appearance cosmetically.
That's why we recommend you topcoat it.
CAN I APPLY POR-15 OVER OTHER PAINTS?
Yes, but you will lose the important benefits of POR-15. You must remember that ordinary paints
are weakened by exposure to moisture. POR-15 can't stop rust if it isn't in direct contact
with the base metal.
CAN POR-15 BE USED WITH FIBERGLASS?
Absolutely. POR-15 is fully compatible with fiberglass and can be used to repair cracks in gelcoat.
It will adhere better than polyester resin and has greater strength.
Use also with fiberglass cloth to make super-strong surfaces in rusted-out areas.
Be aware that POR-15 doesn't contain styrene and thus cannot melt fiberglass cloth
like polyester resin does.
