Right, I wish to make GRP panels for my car as weight saving is my next step with it and I fancy having a go. I will start with the boot lid and then do the bonnet. I will use the respective panels as a plug, make a mould from them and then make panels from the mould.

The panels I have are not perfect by any means as I am dealing with 30 year ols stuff here. Now, I am not obviously into the concourse scene but I don't really wish to replicate all the surface defects either. What is the best way to restore the paint back to a 'mouldable' condition?

1. T cut / cutting paste.

2. Wet 'n' dry various grades and eventually polish.

3. prep and repaint.

4. Brush paint with something like yacht varnish then rub down.

Don't forget that the original panel does not have to look good - it just needs a decent finish to mould from. The surface I have has scratches. Some are quite deep but dont go through the paint. If you can imagine 30 years of debris going through a car wash type of finish. It was very oxidised but a T cut has brought back a shine but has now exposed a surface that is very aged.

Your thoughts and ideas on how to get the best result please
