Time to Ask Your Tape,<br />

“What Have You Done for Me Lately?”<br />

In almost every industry, people continually look<br />

for ways to increase performance levels while<br />

lowering costs. In the paint and body shop business,<br />

the solution may be as easy as upgrading a tool you use<br />

everyday to something that lasts longer and/or gets<br />

better results more consistently. Take, for instance,<br />

masking tape.<br />

In today’s changing market,<br />

new paint chemistries and higher<br />

temperature bake cycles place great<br />

physical demands on masking tapes.<br />

In the automotive refinish industry,<br />

applying masking tape accounts for<br />

six percent of labor revenue generated<br />

on repair orders, or $56 on a<br />

typical repair order of $2,000. Since<br />

productivity equals profitability,<br />

consider how much time is spent<br />

performing compensating behaviors<br />

caused by the performance limitations<br />

of low priced masking tapes.<br />

Megan Scherb, masking solutions<br />

business manager for 3M Automotive<br />

Aftermarket Division, explains that<br />

most painters, without realizing it,<br />

have changed their behavior<br />

to compensate for the<br />

limitations of lower priced<br />

tape. She notes, for<br />

example, that before<br />

spraying, painters<br />

typically inspect the<br />

vehicle to ensure the<br />

masking tape has<br />

not lifted since<br />

application. If it<br />

has, they must<br />

spend time pressing<br />

the tape down in<br />

order to prevent paint<br />

blow-by. Compensating behaviors<br />

such as these require extra time that<br />

could be used more productively<br />

on revenue generating activity.<br />

It seems that to save money in one<br />

area (labor) you must spend more<br />

money in another (supplies), but<br />

sometimes the costs for better materials<br />

are minimal compared to productivity<br />

gained, so it’s important to do your<br />

research and compare costs. To illustrate<br />

the productivity advantage that<br />

Scotch ®<br />

Performance Masking Tape<br />

233+ brings to a paint job, 3M has<br />

designed an interactive value analysis<br />

tool. The tool helps the shop owner or<br />

manager understand the value of the<br />

time gained by utilizing the shop’s<br />

specific operating costs. “Masking<br />

tape can have a big impact on labor<br />

revenue while contributing a relatively<br />

small amount to material costs.<br />

Because of its excellent performance,<br />

using Scotch ®<br />

Performance Masking<br />

Tape 233+ may improve masking<br />

productivity up to 10 percent per<br />

repair order by eliminating extra<br />

steps,” says Scherb.<br />

Scotch ®<br />

Performance Masking Tape<br />

233+ is ideal for all body shop paint<br />

masking applications. According to<br />

Scherb, its balanced construction<br />

provides excellent adhesion with clean<br />

removal—even from difficult surfaces<br />

like EPDM rubber moldings,<br />

after contact with moisture<br />

and chemicals or prolonged<br />

outdoor exposure—all<br />

qualities that can contribute<br />

to increased productivity.<br />

No matter what method is used<br />

for preparing panels for clearcoat and<br />

color blends—traditional DA sanding<br />

discs, wet sanding sheets or scuff<br />

pads—all present obstacles to achieving<br />

a premium finish that results in an<br />

undetectable blend. For example,<br />

scuff pads conform very well to the<br />

panel surface but do not remove all<br />

gloss which can result in clearcoat<br />

adhesion failures. Scuff pads also have<br />

a tendency to leave deep scratches<br />

which may show through on metallic<br />

and pearl colors. Abrasives such as<br />

DA Discs and wet sanding sheets sand<br />

aggressively and remove more gloss,<br />

but do not offer the conformability of<br />

a scuff pad. This lack of conformability<br />

often leaves shiny spots that remain<br />

in the lower areas of the texture or<br />

“orange peel”. To remove this<br />

remaining gloss, the technician will<br />

not only spend additional sanding time<br />

but also increase the risk of sanding<br />

or “burning” through on an edge,<br />

contour or body line. The result is<br />

additional time spent reworking this<br />

previously undamaged area.<br />

3M, the industry leader in abrasive<br />

technology has recently introduced the<br />

company’s most advanced product for<br />

clearcoat and color blending. The<br />

3M TM<br />

Trizact TM<br />

Hookit TM<br />

II Blending<br />

Disc is a foam-backed abrasive disc<br />

designed to conform to the sanding<br />

surface with minimal risk of burn<br />

through on edges, contours or body<br />

lines. The foam backing allows the<br />

disc to conform and sand deep into<br />

orange peel with minimal texture<br />

removal while producing a consistent<br />

matte finish with no “shiny spots,”<br />

something that is difficult to achieve<br />

with traditional DA discs or wet<br />

sanding abrasives. The finish left by<br />

the Trizact TM<br />

Hookit TM<br />

II Blending Disc<br />

makes deep scratch and adhesion<br />

concerns a thing of the past.<br />

The key to Trizact’s excellent<br />

performance is the combination of<br />

its foam backing and unique mineral<br />

construction, which is made up of<br />

micro-replicated, pyramid-shaped<br />

structures. This construction ensures<br />

that fresh mineral is exposed at a<br />

uniform rate, extending the life of<br />

the product while maintaining a<br />

consistent level of cut. Most<br />

importantly, the uniform scratch<br />

pattern left by the Trizact TM<br />

Hookit TM<br />

II Blending Disc allows metallic and<br />

pearl colors to lay down uniformly<br />

resulting in blends that are virtually<br />

transparent which will certainly appeal<br />

to your customer and increase your<br />

shop’s CSI.<br />
