as tensile strength, UV stability, and tear strength. It is not
cheap epoxy or polyurethane with filler and solvents added to reduce
How does Al's Liner compare to the big name, franchise
With a few exceptions, Al's Liner represents a new generation of
polyurethane linings. Most of the big name franchise liners use very
old and out of date technologies. Al's Liner is more UV stable and
tougher than Rhino, Line X and blows the doors off the liners like
Reflex, Armor thane, etc. Since you control the application it's
very probable that no one, even the pros, can match your Al's Liner
Is Al's Liner hazardous?
Al's Liner was engineered to be very safe to use. There not a safer
coating on the market, but you must be responsible and avoid
prolonged skin contact or inhalation. Your lungs were designed for
clean air, not dust, smoke or chemicals. Spraying in a well
ventilated room and wearing a good 1/2 face respirator with chemical
cartridges is a wonderful start.
What will I need to spray Al's Liner?
It could be sprayed with a number of guns, but we recommend using

maintenance. It will last forever and was designed by Al's to give
you great results.

fibreglass, and metal. Some surfaces may require scuffing and

any automotive pigment including pearls or metal flakes to match any
color. Call our technical support team to discuss custom colors.
How durable is Al's Liner?
There is no coating that is more durable. There never has been and
probably never will be. Al's Liner is the top of the food chain when
it comes to spray-on polyurethane linings
Is Al's a rust protector and/or does it prevent rust?
Al's Liner bonds directly to the substrate so no moisture or air can
get in. If it rusts, it will have to come from the backside. Al's
Liner is a little over qualified as an undercoating. No undercoating
or rust prohibitor has the physical properties of Al's. They are not
intended to have good physical properties.
How long before I can use my new liner?
Al's Liner is dry to the touch in 1 hour. Light duty use in 24 hours
and heavy abuse in 72 hours.
Does Al's Liner have a warranty?
We warranty Al's Liner to not deteriorate or degrade in any way. The
warranty does not cover physical damage and the application is up to
you. If you do not mix it properly or prep the surface correctly,
that falls under the applicator. Be sure to read the mix and spray
How do I prepare the surface to spray?
Wood requires no preparation. Fiberglass and metal need to be
scuffed with 36 grit or coarser medium. Sand blasting will give you
a great surface. Wipe clean with a good solvent to eliminate surface

Can I repair my liner if it gets damaged? If so, how would I
go about it?
Al's Liner bonds very well to itself. Minor damage can be repaired
with a brush. Major damage will probably need to be sprayed. Al's
can also be used to repair other bed liners or as a top coat to
extend and save your existing bed liner.
How many square feet does Al's Liner cover, and how deep
would it be?
It's simple arithmetic. Al's is 85% solids so it will cover 22 sq
ft. Per gallon at 1/16" thick, 44 sq ft. Per gallon at 1/32" thick
(31 mils) or 88 sq ft. If you want more coverage, you will sacrifice
Can I mix sand into AL's Liner for more of a non skid
Yes, but you might sacrifice toughness. Since Al's Liner is stronger
than sand, consider changing spray techniques to obtain a rougher
surface. Our tech support will be more than happy to help.
Can Al's Liner be painted over?
Yes. Use a polyurethane paint for best results.
Will Al's Liner hold up against gasoline, diesel fuel, or
other petroleum based products (such as motor oil)?
There is no better polyurethane against petroleum. The only time
there is an issue is if you know the products will pool and set on
the liner for long periods of time. If pooling is going to take
place, you are better off with an epoxy coating.
What about bare metal, how do you prep it?
Scuff the metal with 36 grit or coarser media and/or blast then
apply a light coat of etching primer. Spray on a light coat of Al's
primer and spray
