I recently purchased a lovely pair of fibreglass laminate wings from gt4suspension for my ST165 and it has made me think about making some of my rust heavy trim into non rusting fibreglass. I have looked up a lot on the process thanks to http://www.ecfibreglasssupplies.co.uk 's guides but was wondering if anyone here has done anything like this and thus knows the results or anyone who can simply think of any possible problems in the process/ end product?
Any thoughts are welcome and thanked.

All our electric vehicle bodies are fibreglass which we have manufactured professionally from moulds made by us originally.

The process is to make a full size model of what you want (in your case the original piece). A mould is then taken from that in fibreglass, and this is then used to manufacture copies of the original in fibreglass.

There are limitations -

The product must be able to come out of the mould - i.e. sides need to be tapered. If this is not possible, the the mould needs to have a number of splits put in so each piece can come off once unbolted.

You need to be able to get an arm / hand into all areas to be able to lay in the glassfibre.

Sharp corners are very difficult to get any strength and will often have air pockets.

p.s. there are alternatives.

If you have intricate shapes. You can use a 'rubber mould'. A number of varients, but essentially the mould is flexible so can be stretched off shapes that would stick in a solid mould. A number of ways of doing this.

You can also cast shapes using 2 part resin or expanding foam. e.g. I have just made some soft rubber bumpers to bolt on the front of our vehicles to solve a safety problem on one of our rides.

A good contact is bentley chemicals. They are very helpful with advice etc.

Any thoughts on how to replace rusted out brackets on the trim is also helpful. Can we still buy them from Toyota or?

Not sure mate.

all you can do is supply toyota with a part number and find out:
