evening all,

i was looking at the fit of the interior body panels on the rush tonight and i noticed that they needed a little trimming, i used one of those small dremel grinders to take off some of the fibreglass but it has left a wonky edge,

what is the best tool for cutting/ trimming fibreglass panels and to get a stright edge?

ATB chalkdust

p.s if i am correct fibreglass panels are also known as GRP panels, what does GRP stand for?

Glass reinforced plastic. Don't know about the rest though

Glass Reinforced Plastic (i think)
I think you would be better using something bigger than a dremal say a grinder or a file.

jigsaw with a an acrylic blade worked for me

I mark the GRP where I want the cut, then use what ever method seems appropriate to cut it (hacksaw blade, dremel, etc) to get close to the line, then finish up to the line with a flapwheel on a curve or a flat file to give a straight edge

You can cut GRP with a tungsten carbide jigsaw blade (the powdery looking one)The most used tool in my 'bodyfitting box' is my B&D Powerfile. I can't recommend it highly enough. You can trim, shape and even plunge holes through GRP and it's pretty good on steel too.

diamond tipped disk on a grinder.

A steady hand and a diamond wheel on a dremel has always worked for me.

Going slowly tends to make the edges wonky.

GRP-Glass Reinforced Polymer

Normal metal cut-off disc on an angle grinder. Key with glass is high speed and fine cutting medium, i.e. not a coarse jigsaw blade. And please wear suitable protective equipment - it really is nasty stuff in dust form.

Diamond wheel in a small angle grinder is the best way to cut a good straight edge.....and beleive it or not those cheap as chips £2 specials for cutting tiles work a treat.......unless you really want to pay £25+ for one

Flap disc in a grinder to knock the edges down then finish by hand with production paper to nib the sharp edges off.

GRP = Glass Reinforced Polyester

I used a tool made by fern(?) its a multitool similar to a dremel but it vibrates as appose to spin, it comes with loads of attachments, its beetter thana dremel or grinder and cuts like butter with lest dust and no slipping or unwanted marks.
