We often get asked this question and here are some answers
to questions we often get asked.
One litre of POR-15 Rust Preventative Paint (RPP) will cover
approx 10 sq metres (per coat) on metal and about 8sq metres on concrete
and wood. You need to give it two coats and three for Marine
/ Industrial applications.
Using different colours for each coat often makes it easier
to see where youíve missed.
If you donít sand blast, use the Marine Clean and Metal
Ready, Prepsol and POR-15 don't work together as it is a
solvent base cleaner. Use MARINE CLEAN.
Q. I am doing up my chassis. What do I need?
A1. Non sandblasted, get as much of the old paint off
as you can (no good putting good paint over old stuff that
is breaking down or already rusting.). POR-15 will go over
rusty surfaces and old paint (as long as the paint is keyed
well with sandpaper).

Follow the instructions
This will do a normal car chassis two coats.
A2. If itís going to be sandblasted, donít prime,
apply POR-15 directly on to the sandblasted surface (it
wants to bond directly onto metal) even if you have slight
surface rust occurring after sandblasting, POR-15 actually
keys in better.
Two coats 3-5 hrs apart.
Follow the instructions.
Q. Iím doing my whole car what do I need.
A. You will need to key the surfaces well with a 600
or rougher sand paper and then use the
Marine Clean and
Metal Ready per the
instructions followed by two coats of POR-15 (RRP).
Due to the size youíre working on you will probably have to

Q. I want to do touch ups.
Super Starter Kit is
great for this as it gives you everything you need to do up
to a .5 sq metre 2 coats. The kit comes with Marine Clean, Metal
Ready and POR-15 (RPP) plus brushes, gloves and
You can also buy the
six 100ml cans with a choice of colours (black, grey, sliver
or clear), itís cheaper than buying six individual 100ml
tins. Good to have on a boat.
Super Starter Approx $35.00
Six Pack Approx $87.00
Q. Can I apply POR-15 (RPP) over existing paint?
A. Yes you can, after keying the old paint with
400-600 sandpaper and then using the Marine Clean. Just
always bear in mind youíre putting a new good paint over an
old one and if the old coat gives way it will take the
POR-15 with it.
Q. Do I need a top coat?
A. If you are doing areas that are not exposed to UV,
i.e. chassis, gearbox, suspensions etc then two coats of
POR-15 RRP are all you need.
If they are exposed then you will need to top coat the
POR-15 with one of our products
Blackcote (gloss black)
Chassiscote (semi gloss
black) or use the
/ Acid 8 and apply any type of paint. Remember both
these are linking coats only and not fillers and should be
You can also apply a dust coat of your final coat primer
while the second coat of POR-15 is still tacky (2-3hrs) and
then go ahead with your choice of top coats.
Q. Why do I need two coats of POR-15 (RPP)?
A. When painting spray or brush you tend to leave
ďHolidaysĒ in the paint, small holes or gaps. These will
allow moisture to get to the metal and a rust spot will
occur. You also need a reasonable depth of coating which one
coat doesnít give you.
Q. Can I brush or spray POR-15?
A. You can do either but if youíre spraying you will
need our Solvent to thin at approx 15-20%.
However weíve discovered from users that one of the major
selling points of POR-15 is that if brushed in a flowing
motion you can get almost a spray finish, this means you can
do it in your garage / shed. No special brush is required.
Chassiscote does not brush on as well as the POR-15 (RPP) or
Blackcote. A small amount of solvent (5%) helps it run out
Q. Iíve used Metal Ready and itís come up with an
orange rusty look?
A. That is exactly what it should look like, orange
with a bit of salt and pepper.
Due to the presence of salt, and moisture, special care
needs to taken to ensure a rust proof finish.
The number one enemy for steel is moisture so the BIG MUST
here is to get the metal DRY before painting. Heat guns,
Hairdryers, blow torches etc should be used, you will often
see the water bubbling out of the rusty steel as you dry it.
Itís also no good leaving the prepared job out in the sea
dew overnight to paint the next morning. Any moisture left
on the steel WILL come back as a rust spot. Badly pitted and
flaky rust, store water in good quantities.
The other mistake people make is they pull the boat out of
the water to get a quick paint and anti foul (slipway time
costs money, I know) but the keel to be painted is saturated
with water and not given the time to dry out. This will not
give good adhesion nor will POR-15 work like it should.
Cleaning with Marine Clean and etching with Metal Ready both
go a long way to help POR-15 RPP adhere to the surface
Preparation is everything. In some cases it may be better to
paint directly onto dry rusty metal than introduce more
moisture in the Marine Clean and Metal Ready; it depends on
where the job is and what the conditions are.
Planning for marine work is important as you need to get
three coats of POR-15 on 3-5 hrs apart and then your top
coat if youíre using one.
Q Can I use POR-15 on wood?
A. Yes POR-15 will give you a very good tough finish.
Remember itís not UV stable so if itís exposed, it will need
top coating. Work on about 8 sq metre per litre.
Fuel tank repairs
Our repair kit is three part and included instructions
should be followed.
Sun drying is NOT getting it dry the moisture goes from the
bottom to the top. Blow it dry, hairdryer / heat gun.
If the tank has leaks in the seams, after applying the Tank
Sealer apply slight air pressure to the tank to force the
sealer into the cracks.

Bike Tanks (up to 20 Litres) $ 75-00
Our recommendation is to sand blast or key it with sandpaper
and use the Marine Clean and Metal Ready and then apply two
coats of the Blackcote for a good glossy black finish. We
donít feel you need to use the POR-15 (RPP) first, as in
most cases bikes donít have a major rust problem.

Q. My Por-15 has bubbled.
A. POR-15 lets off carbon dioxide as it cures. If
coating is too thick or the second coat applied too soon it
will bubble. Wait for it to harden and sand back and apply
Q. POR-15 doesnít seem to have adhered properly to
A. It hasnít been keyed (sandpaper) properly or Metal
Ready wasnít used, or both.
Q. My top coat seems to be frying on the Tie Coat.
A. The Tie-Coat hasnít cured, probably because it was
put on too thickly and if this is the case it can take weeks
to cure up. With both Acid 8 (cures quicker) and Tie-Coat
they should be just a little more than a dust coat.
Q. I have rust bubbles coming through.
A. The metal wasnít dry prior to painting or only one
coat was applied.
Q. Iíve left the POR-15 (RPP) for more than 24 hrs,
can I recoat it?
A. The optimum time for re coating POR-15 is 3-5
hours. The adhesion starts to fall off after that. Any time
after 24 hrs we recommend you lightly sand the gloss off it
and the re coat.
