Introdução

0:00

Paint the mold using two part polyurethane paint

0:10

And use masking tape on the sides to avoid the bag to open

0:35

This part is a hood of the motorglider Ximango

1:06

and a breather fabric that helps the air to flow

1:34

I round the corners using epoxi resin with microballoons

1:51

A small plastic bag helps to apply the resin

2:11

The first layer of fiberglass is the most difficult to apply

2:57

Before the third layer, I use some strips of fiberglass for reinforcement

3:43

These reinforcement help to strength the part and don't weight too much

4:01

The method is the same as putting the fiberglass

4:44

Take a special care on the corners

4:49

The internal surface looks like a sandpaper

6:53
