Hi,

Basically im wanting to build a crazy v8 mk2 mr2 with custom body kit, front and rear clam type boot/bonnet, slightly lengthened and a tad wider.. can you advice me on the type of carbon fibre would be best suited for looks and light weight? how much carbon fibre would be needed to do a pretty much an entire outer shell? also wanting to custom engine parts / inlet etc and a carbon dash... i've done alot with fibre glass but i think my project needs to be carbon as im wanting to show it on completion, advice on materials and prices would be great.

Thanks

Gary

HI,

On the movie you use GC50 Compatible Epoxy Polyester Gelcoat. What to use to  activate it to stuck CF to the surface.

Then on the bottom of the bonnet to use another spray  stuck CF perfectly to the surface. What is spreyyou useing?


Thank you very much and best regards

Hi Sawral,

On the movie you use GC50 Compatible Epoxy Polyester Gelcoat. What to use to activate it to stuck CF to the surface.

This is a complicated one and something that's haunted us a bit since we made that video. We shot the video over last Christmas with a 'prototype' version of the GC50. That version of GC50 did become tacky when a small amount of acetone was sprayed onto it and so we used this method to tack down the carbon to the gelcoat. Since then, we had to make some changes to the GC50 in order for it to stay receptive to resin for longer and when we made these changes, this bonus effect that the gelcoat became activated by acetone doesn't really exist anymore. The GC50 that we finalised and put on sale does not behave in this way.

Instead, to tack to the mould surface, whether there is gelcoat there or not, you will need to use an epoxy compatibel spray tack like the Zyvax product (which infortunately is not currently available) or by mixing up some epoxy resin with methylated spirit and spraying it onto the mould or gelcoat (as we've described many times before on this forum).

Then on the bottom of the bonnet to use another spray stuck CF perfectly to the surface. What is spreyyou useing?

This would be the Zyvax Stay-Z product, see above.

I hope this helps and sorry for any confusion we cuased with this. I'll add some captions to the video to make this clearer.

mixing up some epoxy resin with methylated spirit and spraying it onto the mould

What proportion of epoxy resin to methylated spirit use to the mixture?

About 10-20% methylated spirit added to epoxy infusion resin that has been mixed with the correct amount of infusion resin hardener already should be enough to thin the resin sufficiently that it will 'mist' through a trigger press spray bottle. It's not a exact science, just add a few drops at a time until you have a consistency that will spray.

Don't be tempted to use acetone, white spirit or turps. Methylated spirit (denatured alcohol) or 100% alcohol is needed for this.
