Q. What is the material ?
A. The material is thin, clear, self-adhesive Polyurethane that is
approximately .012 inches (.305mm) thick. Since it is clear it will
not change the cosmetic appearance of the aircraft
Q. Will it turn yellow ?
A. No, it will not turn Yellow. The material is aliphatic and it is
not affected by ultraviolet light.
Q. Do you sell direct or must I buy from a distributor ?
A. You can buy direct or through one of our dealers or stocking distributors
Q. What is the lead time for delivery ?
A. We stock every catalog product, every day. If we have an order by
3 PM Eastern Time we can ship that day.
Q. Can I get a discount for larger orders ?
A. Probably, please call to discuss your need.
Q. What is the shelf life ?
A. PM Research, Inc. manufactures and distributes erosion protective
masks and leading edge tape. These products are manufactured to our
specifications and offered off the shelf for our customers' use. Our
high standards regarding quality and service have been the primary
factor in making PM Research the leader in radome erosion protection.
Although we have no control over our customers' atmosphere or storage
conditions, we recommend the following:
1. Keep product sealed in its original box.
2. Do not store anything else with or on the product.
3. Store the product in an atmosphere that is clean and dry.
4. Store the product at room temperature.
5. Continually rotate product stock.
If above conditions are met, shelf life is not an issue since it will
be greater than five years.
Q. What FAA form or approval is required to install erosion
protective masks (boots)?
A. Since the installation of PM Research, Inc. masks is similar to
applying a thick coat of paint, the PM Research, Inc. line of Erosion
Protection Masks (boots) can be installed and the aircraft returned
to service in the same manner as if it was just painted. Our products
are not structural in nature and are not required to be FAA approved.
We are not required to have a STC and we are not required to be PMA
approved. Form 8130 is not required.

Q. Is the product traceable ?
A. The erosion mask products are produced by PM Research Inc. in
Wellsville, NY and are fully traceable. We do offer Certificates of
Conformance at no charge.
Q. How is it installed ?
A. The material is self-adhesive. The backing is peeled off and the
product is installed wet; with a solution of distilled water, alcohol
and dish washing liquid. This prevents the material from sticking
until the location of perfect fit is located. The moisture is then
pressed out with hands and also with a plastic squeegee. A trim line
is established and the mask is trimmed with a sharp blade.
Q. How soon can I fly after Erosion Protection is installed ?
A. 60 percent adhesion is obtained after 1 hour and near 100 percent
after 24 hours. You can fly 1 hour after installing a Radome boot
because the slip stream will hold it on and not try to peel it off.
For other products with edges that are exposed to the force of the
relative wind, a longer dwell time is required
Q. Is maintenance required over the life of a boot ?
A. Clean and wax periodically as required. We recommend that you use
full strength Knight's Spray Nine ® or full strength Ultra Mr.
Clean ® to clean the mask (boot). Use a non-silicon based paste
wax after each cleaning. Waxing will make cleaning easier and prevent
bugs from staining.
Please note: Most waxes have a small amount of silicone to
improve shine. These are OK! It is the silicone based waxes that
should be avoided to prevent problems with painting the aircraft in
the future.
Although PM Research does not recommend any particular brand, we know
that Collinite Corp. (315) 732-2282, produces a couple of fine waxes
which come highly recommended. The one we suggest is; Collinite No#
SS 126 Liquid Sapphire Auto Wax. Another brand is Meguiar's. You can
order these directly from them or through distributors.
The user should determine an appropriate schedule to check for damage
(i.e., cuts, blisters, perforations, edge lifting, etc.) At the first
sign of damage, the mask (boot) should be replaced with the best
protection available... A genuine PM Research protective mask (boot).
Q. How do I remove a boot that needs to be replaced ?
A. Carefully score the top surface of the mask with a razor blade
knife dissecting the mask (boot) into triangular pie-shaped sections
approximately 4" to 6" at the base. Pull sections off at
approximately a 180 degree angle.
If adhesive residue remains after removal of a mask (boot) from a
PAINTED SURFACE, clean residue off with a rag saturated with a
mixture of 75% MEK (methyl ethyl ketone) and a 25% toluene. Scrape
residue off with a platic squeegee. NOTE: Follow the solvent
manufacturer's safe handling procedures to prevent possible damage to
the painted surface. Be sure to check with the the paint manufacturer
to make sure that this procedure will not affect the paint you are
using in any way.
To remove residue from a PLASTIC LENS, DO NOT USE MEK (menthyl ethyl
ketone) OR TOLUENE as they may damage the plastic. Use denatured
solvent alcohol and some elbow grease.
Q. Do airlines or the military use these products ?
A. Yes they do. PM Research products have been installed on the
aircraft of more than 200 airlines through out the world. We have
product installed on jet fighters, cargo planes, helicopters and
UAV's. The same tough material that is used on civil aircraft stays
on military planes at Mach speed.
Q. Can I protect prop blades?
A. Since PM Research cannot control the installation of our products,
we Do Not Recommend they be used to protect prop blades. Improper
installation might result in an "Out of Balance" situation.
Considering the serious consequences which could result, PM Research
will not assume any risk or liability whatsoever in connection therewith.
Q. What is included with the mask (boot) ?
A. The installation kit includes: an 11 page Shop Manual of
instructions including photographs, a clean squirt bottle, a plastic
squeegee, a water soluble marking pen and a spout cap for measuring
dish washing liquid.
Q. Are additional materials required for installation ?
A. Yes, you will need the following items::
1. 1/4 inch masking tape.
2. Wetting solution consisting of
4 oz. Isopropyl alcohol, 70 percent by volume (common rubbing alcohol)
12 oz. Distilled water
