Fibreglass costs
I was wondering how much it'd cost for all the fibreglass and resin (ballpark figure) for a grp body around this size:

a lot more than you'd think.
try a suppler for boat building materials as they often are the cheapest and have large turn overs of materials. They also don't tend to sell
rubbish.

Ballpark - I reckon £2k would easily see it done in CSM and polyester. From there go upward depending on cloth and resin chosen.
Or you could just keep your eyes open, twice my Dad has managed to pick up several hundred meter rolls of CSM for absolutely bugger all (£50 last
time, still has enough left to build an entire car!)

as a really ballpark figure, the pic in my av has a surface area of roughly 16sq m, so depends on how thick and what weight cloth you want to make it
out of. Allowing say 3-4 layers plus additional for strengthening area's, "bit's n bobs" - 60 odd sqm? say 300gsm cloth,
18kg?
That seems a bit light - is my shoddy maths showing through again?
Allowing ~4:1 resin to ratio that means 70-80kg resin.
which brings us to a figure of £250!!! Making the mould I'd add double that.
Shows I've been playing with carbon and the more exotic fibres for too long 
In fact at that price I'm tempted to start playing with glass at lot more.

People like the hot rod dudes have some novel and fast ways of making one of body’s. For example one method I have seen involves making the mould in
plaster, that’s finished with vanish. Laying the glassfiber over it. Once set the plaster is washed away, and then the outside of the glass shell is
sanded down, etched and painted. Rather quicker than the old standard method and used only half as much materials, also leaves a shiny surface on both
sides and no fragile gel coat to crack.

I'd say £2k was a bit on the expensive side!! I bought enough gear (from CFS) to make a rear half body tub for my plastic car for £125 and I
still have some left over!

But.. Do you have a mold, I should imagine this will cost a bit to make, possibly a lot more that the GF..

The 2 k was a price we had made up for doing a small boat 16 feet. That was for the mould and a boat. Granted you may not have to make everything as
thick as you would for boat stuff.
That was also using decent resin and matt. Second quality stuff would be cheaper.
Its still not cheap though.

If you are making moulds, you need to allow a good chunk more, as you tend to make 'em quite stiff. I would reckon on £300 for the material in
the moulds (Assuming you had a part to take a mould from) then another £200 for the panels themselves. Remember you would need gel coat (unless
spraying afterwards), which means you might also need a barrier layer/vail cloth to mask the CSM 'print through'. Factor in a big tub of
filler, and lots and lots of time to get is perfect!
Delinquent - how much resin!? Are you casting the panels?! 4-1? More like 2.5:1 if you are any good!

 I rarely do any CSM stuff, just know it takes more than the cloth I use so upped it a bit, plus I tend to make my own gel from resin so allowed a
bit extra for that, then rounded it up for lack of experience for the OP meaning likely lots of it left in pots gone hard.
Possibly a bit OTT though!

My very rough estimate for surfacing a plug, making the molds and the first body is
90 kg CSM
30m2 surface tissue
200 kg Resin
5 kg surface gell coat + pigment?
5 kg surface tooling gell coat + pigment
You also need fairing past / filler/ acetone / wax / tools etc
Adds up quick
When i got a quote on the above a year ago (excluding tools) it came to the equivelent of about 600 UKP, but note that the price of resin has gone
ballistic lately, following the oil price.

You can do it quickly. You can do it cheap. You can do it right. – Pick any two.
