PAINTING and MAINTENANCE
Painting the Shells:
Wash the bodies in warm water with
dishwashing liquid. This removes the vegetable oil which is used
as a release agent during the moulding. After washing rinse under
normal cold water and allow to dry.
For best adhesion of the paint, rub
back the surfaces to be painted with a very light wet and dry
sandpaper (600 grit) is best. Do not rub back the clear windows.
The best result can be obtained by
spraying or hand painting with polycarbonate or acrylic based
paints. Both of these are water soluble and flexible and give
great results. Turps based enamel can also be used, but it is
more brittle. Do not use lacquer based paints or Pactra polycarbonate
paints as these are lacquer based (They make the plastic very
A coat of thin PVA glue over the inside
painted surfaces helps to keep everything in place during the
rough and tumble of racing.
PETG is a very tough plastic and will
resist most average knocks. It will however, tear if it put into
a shear situation (the same as polycarbonate-Lexan). If this
happens, tape the tear in place from the outside, with masking
tape and repaint if necessary around the tear. Then run a bead
of PVA glue along the tear with a toothpick. Allow to dry for
24 hours and this will hold under most situations.
If you sand some of the clear areas
of the shell, these can be repaired by coating them with clear
gloss acrylic paint. This fills up the scratches and smooths
them over so as they are not visible.
