works up to a point where so much hardener is added that the mixture
never hardens. Follow the general directions on the Bondo can for fast
setting Bondo. Mixing is done on a scrap piece of cardboard or plywood
(or almost anything), using a hard squeegee or putty knife. A blob of
Bondo is scooped out of the can and dropped on the mixing board. A small
amount of hardener is squeezed out onto the blob and then you mix to an
even color. You will mix the blob for about one minute. You will then
have two to three minutes to apply it before it hardens.
..... Be sure to clean the board and putty knife off before the Bondo is
completely hard. MEK will clean Bondo off your putty knife and squeegee
if it isn't completely hardened.
PEEL PLY
..... Peel ply is a layer of 2.70z dacron fabric which is laid up over a
fiberglass layup while the fiberglass is still wet, and is later removed
by lifting an edge and "peeling" it off. The most convenient form of
dacron to use is "surface tapes", normally used in covering fabric
aircraft. These are available in rolls. You wi11 need at least one roll,
2" wide. Peel ply is used for two purposes:
(1) Peel ply any area that will later be structurally attached to
another fiberglass layup. Once the dacron is peeled off, the
surface is ready for another layup, without sanding. If you do
not use peel ply, you will have to sand the surface completely
dull (no shiny spots). This sanding is hard, itchy work and
ruins the strength of the outer ply of fiberglass.
..... Note that to peel ply the trailing edge overlap area, the peel ply
is the First ply made to the foam core, Lay a strip of dacron down on the
overlap notch and secure it with tacks or staples so it doesn't move when
you layup the skin.
(2) The second use for peel ply is to transition the area where
the top ply of a layup terminates on the fiberglass surface.
..... Refer to the adjacent sketches. If the top ply edge is laid up bare
it results in a rough edge that can delaminate if a little dry. Sanding
the rough edge is hard, itchy work and usually results in damaging the
adjacent surface. If the edge is overlaid with a strip of dacron during
the layup (lay on the dacron and wet out by stippling or squeegeeing) it
will make the edge lay down flat and will form a wedge of epoxy to
smoothly transition the edge. After cure, peel off the dacron. The result
is a beautifully transitioned smooth edge with no delamination tendency.
Use this method in all places where a cloth edge terminates on the
surface.
