Does
it really matter what kind of masking tape I use for my paint job?
A.L., via e-mail
Yes. Masking tapes are manufactured in various grades, and buying
an inferior one may jeopardize your work, causing you to waste time and
money by redoing the job.
The
wrong masking tape may have poor solvent resistance or glue, resulting
in paint “creep” under it, causing a poor line. When taking
the tape off, too much adhesive can remain, causing you to do extra work
in removing it. In addition, any adhesive not removed will create problems
with later applications.
Regardless
of its quality, tape that is left on too long can actually bond to the
surface, making removal difficult. This usually results in damage to the
surface area and, once again, having to do the job over.
While
you may experience sticker shock at the price of some masking tapes, in
the long run you’re better off with the superior product. Check
with your paint manufacturer for its recommendations.
I
was working with epoxy and noticed that the mixture became very hot and
cured much too quickly. What did I do wrong? L. P., via e-mail
You may have
mixed too large a batch, the ambient temperature you were working in was
too warm for the hardener, or your application was put on too thick. Try
mixing smaller batches or transfer the mixture to a container with more
surface area after mixing. Your product manufacturer will most likely
suggest using a hardener designed for warmer temperatures. And finally,
in those areas that require a thick application, fill in with several
thin layers.
The
starter solenoid on my small diesel engine clicks, but the starter does
not run. How do I troubleshoot this problem? M.G., via e-mail
First clean
and tighten all starter and solenoid connections. Make sure all the terminal
eyelets are securely fastened to the wire strands and are not corroded.
If you find any corrosion, make sure you thoroughly clean it off. Then
try starting the engine.
If that
proves a dead end, next remove the battery terminal clamps. Clean them
as well as the battery posts. Reinstall the clamps and tighten them securely.
If the
starter still does not run, connect your 12-volt house battery to the
starter battery with jumper cables. If it’s a no-go, the starter
will have to be replaced. Depending on its condition, you might want to
have it rebuilt and kept aboard as a spare. If you do so, wrap the starter
in an oil-soaked towel to keep any corrosion from getting at it.
