Q) How long can the Diamont Base dry before it is required
to apply clearcoat?
A)
Eight hours, unless you are using BCH2 basecoat
hardener, then you have up to twenty-four hours.
Q)
What happens if the Diamont Base dries longer than
recommended before clearing?
A)
Lightly scuff the Diamont base and apply a light coat of
color or BC100 prior to applying clearcoat.
Q)
How and when should the Diamont Base be sanded to remove
small imperfections?
A)
Allow Diamont Base to dry for 30 min.@ 68F, lightly sand
using 1200 grit of finer.
Q)
What is used in blending Diamont Base for an orientation
coat?
A)
Use either BC100, BC00, BCH2, or over-reduced RFU
clearcoat is preferred, check VOC regulations.
Q)
What is the recommended tape time for Diamont Base?
A)
Allow Diamont base to dry 30 min.@ 68F before using
masking tape.
Q)
Is it necessary to scuff the Diamont Base prior to
applying clear?
A)
No, Diamont is designed as a wet-on-wet process,
provided clear is applied within recommended times.
Q)
What is the interior recommendation for Diamont Base?
A)
Mix 2 parts Diamont color to 10% DH42 or DH46, reduce
mixture 75-100%. Apply two to three coats. Do not
clearcoat.
Q)
How is BCH2 used in Diamont?
A)
By adding 10% to the mixed color before reduction.
Q)
Does the use of BCH2 affect the pot life of mixed
Diamont Paint?
A)
Yes, the potlife becomes 24 hours @ 68°F.
Q)
What is the potlife of Diamont Base?
A)
Unreduced Diamont Base has an infinite potlife.
Q)
Can a flex agent be added to Diamont Basecoat?
A)
No. Flex agent can only be used in undercoats, single
stage topcoats, and clearcoats.
Q)
Can fisheye eliminator be used in Diamont Basecoat?
A)
No. Fisheye eliminators are designed for use in single
stage topcoats and clearcoats.
Q) How does one determine if the primer on a factory
bumper is soluble or non-soluble?
A)
Solvent test all OE and aftermarket primer coats with UR
Reducers by wiping the substrate with a rag. If the
primer softens or dissolves, it is necessary to remove
the factory primer to avoid lifting of R-M primers.
Q)
What are the advantages when using the Polyuroxy (UA97)
and the EP-series epoxy primers?
A)
The UA97 creates a unique three component undercoat
combining the speed of a urethane primer with the
durability and protection of an Epoxy based primer.
Polyuroxy offers advantages in flash off/dry times,
adhesion and corrosion resistance, and is also able to
be used as a W/O/W sealer under the UNO-HD.
Q)
Does R-M have a procedure for applying primer or sealer
direct to aluminum?
A)
Use either DP-Powerfill, or DS30 / DP21 with PH120
hardener for sealer applications. For primer, use a
chromated epoxy primer, DP-Powerfill, or DP20 with PH120
hardener.
Q)
Can you flex an Epoxy Primer?
A)
No. It will not dry.
Q)
Can DS30 be used on a flexible plastic part?
A)
No. DS30 cannot be flexed. It is used on rigid plastic
only.
Q)
What R-M primers can be rolled on?
A)
DP20 2K Urethane Primer, DP21 Color-It Primer, and DP200
Low VOC can be rolled on using approved BASF Roll-On
Primer products.
Q)
Can DP20 be tinted?
A)
No. For a tintable primer/sealer try DP21 Color-It
Primer, or DP- Powerfill series primers.
Q)
What primer should be used on bare metals?
A)
Epoxy Primer (EP589, DE15/40), an Etch Primer
(DE17/DE18), or the DP-Powerfill.
Q)
Can body fillers be applied over DE-Series etch primers?
A)
No. Apply a urethane primer over the etch primer prior
to filler application.
Q)
What can be done to accelerate the dry time of primers?
A)
Selecting a faster hardener/reducer combination (if
applicable) while maintaining proper film build. Do not
use Jet-95, HR5, or other accelerators in primers.
Q)
Is it possible to tint the EP-Series primers?
A)
No, however EP-Series primers may be blended together to
achieve a more desirable undercoat color.
Q)
What happens if a sealer is allowed to flash too long or
not long enough?
A)
Flashing a sealer too long may cause wrinkling while not
flashing a sealer long enough will trap solvents and may
cause solvent pop.
Q)
How long must R-M clearcoats dry before they can be
polished?
A)
Air-dried clears must cure for at least 24 hours before
they can be polished. Clears that have been baked can be
polished as soon as they have cooled down.
Q)
Which fisheye eliminator can be used in R-M clearcoats?
A)
Up to two ounces of R-M 809 Fisheye Eliminator per
ready-for-use gallon of clear can be used to reduce the
surface tension of the paint film.
Q)
What is the proper flex agent for R-M Clearcoats?
A)
The use of DF25 is recommended for flexing the majority
of R-M Clearcoats. Refer to the product’s TDS for proper
mixing ratio and curing instructions.
Q)
How can the R-M Clearcoats be flattened?
A)
Utilizing BC101 in DC76NR, DC88NR, DC92, DC95, and
DC5100 will provide the desired affect based on amount
added. For DC5300 CTR Baking Clear utilize the SM09
flattening agent.
Q)
What additive will duplicate textured clearcoat finishes
(i.e. bumper texture)?
A)
MT900 texture additive will duplicate fine to medium
textures to match OEM textured finishes.
Q)
What is the R-M CTR Repair System?
A)
The SDRS process involves a comprehensive training
program, specially designed spray guns, and a unique
blending solvent (UBR200) that enables small areas to be
blended without clearcoating entire panels.
Q)
Where can additional information regarding the CTR
Repair System be located?

Any painter or jobber with at least one year’s
experience as a refinisher is qualified to take the
training course.
Q)
What are some benefit’s the CTR Repair System can offer
a shop?
A)
Considerable savings in material costs by not clearing
entire panels; SDRS system uses current Diamont
basecoat/clearcoar products; great upsell opportunity
for shops.
Q)
What is the average size of repair suggested when using
the CTR Repair System?
A)
Approximately 1½” in diameter on verticle surfaces only.
Q)

North American Refinish Warranty?
A)
When applied by trained and certified technicians using
R-M Diamont approved procedures and products.
Q)
Is it possible to clearcoat the UNO-HD?
A)
Yes, using one full coat of DC5300 or DC95 clear with
the same or slower hardener/reducer combination.
Q)
What is the blending solvent for UNO-HD?
A)
Use either HR50 or UBR100 to blend the UNO-HD. Refer to
the appropriate technical data sheet for additional
information and procedures.
Q)
Can you use a straight UNO-HD tinting base?
A)
No. You must add 10% SC01; 10% SC10; and 5% HD10 before
adding hardener and reducer.
Q)
Is it possible to intermix clearcoat with the last coat
of UNO-HD?
A)
Yes. Intermix DC5300, DC92, or DC95 with UNO-HD at a
ratio of 1:1. Both should be RFU and have the same
hardener/reducer combination.
Q)
What is HD10?
A)
HD10 Multifix helps control the flow and sag of UNO-HD
colors.
Q)
Should SC01 and SC10 be added to UNO-HD SC403 or SC804
factory pack colors?
A)
No. Factory packs already have binders and driers mixed
in. Just catalyze and reduce.

finishes (ie.: bumper texture)?
A)
MT900 texture additive will duplicate fine to medium
textures to match OEM textured finishes.
Q)
What are the differences between U35 and U40?
A)
UNO-HD offers a 3.5 VOC presentation under the U35
formula designation. 4.0 VOC (National Rule) is
designated as U40. The 3.5 VOC presentations use a low
VOC mixing clear, SC00.
Q)
When can a decal be applied to a freshly painted part?
A)
On air-dried and baked finishes, wait at least 48 hours
before applying stripes. Wait at least one week before
applying large or thick decals.
Q)
What causes fisheyes?
A)
Typically, oil, grease, wax, silicone that remain on the
substrate.
Q)
What causes solvent pop?
A)
Coats of finish applied too thick, flash time too short,
using a hardener/reducer that is too fast.
Q)
What causes orange peel?
A)
Too much distance between the gun and the panel, spray
pressure too low, topcoat applied too lightly, high
viscosity, incorrect reducer (too fast).
Q)
What causes a metallic paint to mottle?
A)
Unevenly applied basecoat, not enough flash-off before
applying clearcoat, or first coat of clear applied too
heavily.
Q)
What causes hazing?
A)
Oxidation, the same process that causes a bare metal
surface to rust, will cause a paint surface to haze.
Hazing usually occurs when there is too much moisture in
the air.
Q)
What factors determine which hardener to chose?
A)
The shop environment (temperature, humidity, etc.) and
the size of the area being painted will determine which
hardener to choose. If 1-2 panels are being painted at
70°, a fast hardener should be used. If two or more
panels are being painted at 70°, a medium or slow
hardener should be used.
Q)

Reducers?
A)
Code Product Name Temperature Range
UR30 Extra Fast Reducer Below 50°F
UR40 Fast Reducer 50°F - 68°F

UR60 Slow Reducer 80° - 100°
UR70 Extra Slow Reducer Above 100°
UR100 Universal Retarder Above 100°
Q)
How much UR100 is recommended for use in R-M clearcoats?

Add 5% - 10% to the clear to slow down the drying time
in extremely hot or humid weather. |
