In his letter on post box, Terry Pollock is talking
about his current projects and says,
"I am using an Australian covering
material on the models. This is an opaque heat shrink material
especially developed for modelling. When you apply it and heat shrink it
then it goes clear. You can then paint it any colour you like."
I thought that sounded quite
interesting and asked Terry for some more information. He tells me it is
called OzCover and it comes from Tony Cincotta at Saturn Hobbies in
Melbourne.
Terry goes on
to say:
"I have used the OzCover product on a
couple of models and can vouch that it is almost indestructible.
"You apply it in similar manner to normal
coverings such as Solarfilm, however it tolerates much higher
temperatures. It is almost impossible to burn a hole in it. It also
requires higher temperatures from the heat gun or covering iron to
shrink it. It starts out opaque and when finished it comes up clear. It
looks fantastic on old-timer type models where you often use transparent
or clear covering on large parts of the wing or fuselage.
"In use it does not sag in the sun. Some
modellers have left models inside their car in direct sunlight, which
can reach over 50 degrees Celsius here in summer, with no sagging. Also
tends to reduce those minor "hangar rash" marks that often
spoil our beautiful models. Painting is very easy with minimal
preparation required. Just a wipe down with acetone to get rid of any
residue. Mask it any way you like. I use standard (real cheap) household
enamel paints.
"I will see if I have a photo of one of the
models I used it on and send it to you. I destroyed my stick model a
couple of months ago when I did the old "pull up when flying
inverted" trick. Was too low to complete the half loop. The
covering material stayed together better than the balsa did in some
areas."
OzCover is available in 3 grades.
OzLite weighs 39gsm and is suitable for everything from light weight
rubber to small R/C models, Ozcover which weighs 80gsm for the larger
models, and almost bullet proof OzTuff at 133gsm for those extra large
models.
