Fiberglass Moulds?

[city_racer]

hello

has any one ever delt with fiberglass moulds before?
What are they like?
How good are they?

[James]

In what respect do you mean? Like how good are they is a fairly broad question.

[city_racer]

i mean like

if i got a fiberglass mould of a city spoiler how good would it be compared to the original one?
how long would it last compared to the original?
and what are the down sides?

[James]

You mean youve got a fiberglass copy of the spoiler or a fiberglass mould of it so you can make a copy?

Fiberglass is a pretty good material, it has pretty good life if the right stuff is used when making it, and its made well. If cheap gel coats and things are used then it can go brittle and crack in UV light.

If its all made properly and everything 10 years life wouldnt be out of the question at all.

The mould is what you make from the original piece and is it's opposite. The mould is then used to fabricate the new part. Many new pieces can be made from the mould provided it is used and protected properly. The life of the replacement part will depend on the build quality and how well it is protected from moisture and UV rays. The new part will have the same surface imperfections as the original part. Hope that helps. Down side is the building process is messy and usually smells. Some of the chemicals are dangerous so skin and eyes should be protected at all times. The catalyst for Polyester and Vinylester resins (M.E.K.P.) can blind an eye in less than a minute if you splash some in there. Your knowledge seems very limited, don't play with it until you study the materials and process fully.
