Small = 1.5 mm (1/6)

£4.00 pack contains
5 rivets per inch. 18 inch long strips. 90 rivets per
strip.
16 strips = 1440 rivets. Each rivets is double type =
2880 rivets.Two rivet types.are in the same packet.
Painted rivets. Stick the self adhesive strip to
the model.
Use a small brush to apply primer or paint to the holes
in the strip.
Peel off the strip when paint has dried. (Only 2 minutes
with primer).
Now ready for painting.
Stuck-on rivets. Save the backing paper from
painted rivets.
Apply adhesive tape over the dots on the paper, rub down
hard with knife
handle. Apply the tape to the model, rub down and remove
the tape.
The adhesive dots are ready to be painted with the model.
The stuck-on rivets are slightly smaller than the painted
type and stand
out more on the surface. The painted type depend on how
thick you
apply the paint. Practice on plastic sheet with both
types, then paint t
hem to see if the result suits the model you are
building. Experiment to
get the right effect.
Scale paneling tapes.
£3 pack. 120 x 12
inch strips.
Stick the tapes to
the model, spray over with primer. A light sandin
then removethe tapes. Leaves a very narrow groove to
simulate panel
lines. Should be done before the rivets.

PRO-SKIN
PRO-SKIN is epoxy-glass sheet which has been moulded under high
pressure and heat. Result is a perfect flat
sheet with semi-matt surface which accepts paint and glues well.
It is waterproof and fuelproof, and will not warp.
When a model has been covered in PRO-SKIN, it will be ready to
paint! Gone will be the weeks or months of
tedious dusty work of rubbing down, messy resin/glass covering,
filling, more rubbing down and so on.
PRO-SKIN gives you a representation of a scale metal skin which
would be hard to achieve normally, and its instant!
When you add it all up, PRO-SKIN is not only MUCH quicker, it is
also cheaper!
I did a check building a 9 foot span pair of wings,
Balsa sheet £35. 1120 gm

Total cost
£91
1640 gm
The cost of eqivalent area in 0.3 ProSkin - £84.
The proskin was a little heavier 1872 gm. but much stronger.
Use for Foam wings, instead of veneers.
Sheet is applied using Polyurathane adhesive. The adhesive has a
foaming action which
fills the slight irregularities in the foam. Leading edges and
wing tips are best made with balsa as normal.
Result is a hard surface ready to paint.
Wing is strong and stiff as it would have been with the normal
veneer/glass/epoxy resin finish.
Built up wings instead of sheet balsa.
0.2, 0.3, or 0.4 mm PRO-SKIN is used according to the size of the
model.
The wing structure is sanded until all ribs and spars are level,
just as you would for sheeting with balsa.
The PRO-SKIN is cut with scissors slightly oversize. (One piece
covers the wing, no joining of sheets is needed).
Polyurathane adhesive is applied to the wing structure and the
skin is smoothed down and clamped or weighted.
The adhesive foams up to fill any gaps and
also give a filleting effect to make a strong bond with the
structure.
The adhesive will be handleable in about 20 minutes, then the
wing can be lifted and the operation repeated for
the other side. The PRO-SKIN will only work where there is no
double curvature, so wing tips and leading edges will
be made in the traditional way. The PRO-SKIN is now ready for
painting!
Alternative adhesive is one hour epoxy with
some filler to thicken it. This allows more time to position the
skins.
It is good practice to slightly roughen the ProSkin suface at the
glue joints.
Hunter wing with top skin fitted.
Hunter
flap only 6 mm thick and completely rigid. Took 15 minutes to
make.
Fuselages, small assemblies, ailerons etc,
anywhere that a flat sheet will fit. Perfect sharp and straight
trailing
edges are easy with PRO-SKIN. Scale hinging for metal subjects
now becomes easy! Hinges can be fitted with our
tiny screws directly under the thin, hard PRO-SKIN sheet.
Hatches? Just cut the hatch in PRO-SKIN, place it on the
surface and mark around with a knife. Cut out, and line the hole
with narrow strip of PRO-SKIN glued inside. Place
the hatch into the perfectly fitted recess and secure with MRM
‘000 ’ tiny screws. Job done!
How?
Foam wings/tails/fuselage panels are
covered in the thinnest PRO-SKIN, using polyu glue.
You must prepare the job well before applying the adhesive to one
side of the foam, spreading with a scraper.
You must work quickly to get the PRO-SKIN in place within 5
minutes. The inside of the skin can be dampened
if you want the adhesive set more quickly. The PRO-SKIN is then
held down with weights, or clamps and left to set.
Adhesives.
Polyurathane sticks very well to most things (even your fingers).
It is very convenient to fit formers in glass fuselages
because it needs no mixing. Just squirt it from the bottle over
the joint and it will form a natural, slightly flexible fillet.
Proskin will work with epoxy resins and cyanos. For an almost
unbreakable trailing edge, just apply normal cyano
so that it wicks between the wing skins. It will set in a few
minutes, then you will be able to knock the trailing edge
of your wing on the edge of your wooden bench. The bench will be
dented, not the wing!
Limitations.
As you might expect, being a perfect flat board, PRO-SKIN cannot
cover compound curves in one piece.
Most wing panels can be dealt with, and the leading edge is most
easily achieved with balsa in the traditional way.
Double curvature wings may be possible by slitting the PRO-SKIN
near the wing tip, but you must experiment with
this. Wings with a change in section, such as the Hunter or
Javelin will require a short slit at the front of the Proskin
You can be sure that many new techniques will be developed with
this new material when ingenious modellers get their hands on itl
ployurathane adhesive is very useful for
all sorts of materials. It needs no mixing, cures quickly and
foams out to form
filleted joints.
