By now, your custom
interior panels, or door panels should have some resin applied to them
and are beginning to look like what you had in mind for your custom car
or truck interior. They should be fully dried, test fitted,
sanded, and cleaned before proceeding to the next steps in this
process. The next few steps involve applying a body-filler,
i.e. Bondo, to the "glassed" portion(s) of your door panels,
then sanding it smooth to achieve a perfectly smooth finish.
Please remember that you
need to wear a dust mask, protective gloves and safety goggles when
working on your door panel project!
The whole idea behind using a body-filler is that it is
easy to spread and fills low spots in your panel easily. It
is also far easier to sand than that of the resin you applied in the
earlier steps. Consider the resin you applied to be the
skeleton of the custom door panel and the body filler is the skin.
After sanding the bondo with progressively finer sandpaper,
your door panels will become extremely smooth and ready for paint.
The next step is to mix up
body filler and apply it in light coats to fill the low
spots in the custom interior panels resin coat.
- Follow the instructions on the can of body-filler to learn
how much hardener to add! Too much hardener will cause the
body-filler to dry to quickly and will make it impossible to spread.
Too little hardener will make the filler take forever to dry!
- Do small sections at a time to avoid mixing up too
much or too little.
