Scratches out of fibreglass

I have been using 1200 grit wet and dry to get the lines down till it blends in with the fibreglass body
I am now faced to get rid of the scratches!
What have other people used to blend the scratches out of the fibreglass as I have been told not to use t-cut, as it will give an age effect to the fibreglass?
Thanks all for any help

2000 grade and farecla G3

And one of these:-

Farecla G3 I’ve heard of this is this like t-cut but for fibreglass only?
also got to get one of them toys!!

g3 used for cutting back fresh paint. its a messy job especially with a machine polisher, take care when using a machine polisher as they can burn through paint very easily.

Polishing compounds can be had from most bodyshops or CFS

Have a look on Detailing World for advice. There are loads of products available without going to the extent of G3. Also a random orbital polisher is a lot safer than a rotary as it won't burn through paintwork.

Ok thank for the help!
If I go for doing it by hand, then what’s the best stuff to use like cloth etc?
Thank again
