Replacetone will work for cleaning containers and tools, but do not use it
to prep the fiberglass. It is non volatile and will not easily evaporate
from the glass surface. Additionally it does not dissolve the resins and
IMHO will not properly prep the surface. Acetone is not very toxic if you
use common sense and don't bathe in it or sniff it to get high. Use
appropriate methods and it is the best material for the job.

I bought some stuff called "Replacetone"
<http://www.aircraftspruce.com/catalog/cmpages/replacetone.php> for
cleanup mostly because it is a lot more "safe" than acetone.
Would this also work as a substitute for acetone for prepping
fiberglass work?

Hi Les=2C
If it is the mating surfaces on the doors halves (page 45-2)=2C the idea is
to roughen the surface for a good bond with the epoxy. I remember using sm
all disk sander with a 25 or 40 grit disk. Again the purpose is to roughen
the surface not remove material.
If you are getting ready to epoxy your doors together both Tim and Deems ha
ve great information on their websites.

Hi
Once again I just have to say that this list is an
absolutely indispensible resource to first time builders like me. Thanks to
all
who chime in and provide guidance.
Here is my next question. When prepping the doors=2C Van=92s
instructs that you =93=94sand the bag side surface=94 of the inner
and outer door shells. After fitting the canopy=2C it seems to me that the
term =93sand=94
could mean a light touch up or sanding to 0.0000001=94. That being said=2C
I
have sanded the perimeters until they are nearly=2C but not quite completel
y smooth.
I didn=92t want to take too much material off. Is this correct or should
these surfaces be absolutely smooth (i.e. no low spots at all no matter how
slight)?
Inquiring minds need to know

Hi Vern
I thought that would be the case but the mating surfaces are quite uneven in
spots. Mating this would leave a very uneven result. Again my assumption is
that the surfaces should mate fairly evenly. Is that correct?
