Made a start on a new lower splitter today (The Mk3)
The Mk1 & 2 were both made from 6mm ply,
The Mk1 was just primed and sprayed gloss black,
The under side of this soon worn down due to rubbing on speed bump's.
The sole purpose of the Mk1 was to get the shape and size right before making the the Mk2 which would be wrapped in Carbon Fibre.
Mk3, Carbon Wrapped.
To try and limit the wear on the under side of the Mk2 both side's were wrapped in Carbon Fibre, On the underside I used a cloth that had Titainium reinforcment strand's and then applied several layers of clear resin, this has held up very well to being rubbed on speed bump's so I'll be doing the same on the Mk3. The top side was then wrapped in 2 twill Carbon, the only
problem was I did'nt wrap the Carbon over the edge which left the edge of the ply exposed, the edges were built up with layers of clear resin.
But due to the punishment the lead edge takes the resin has chipped off in places allowing water to get into the ply and delaminate it.
The Mk3 had to be made from somthing that would stand up to the weather better than the Ply, I wanted to use acrlyc plastic sheet but it is very expensive so I opted for a hi density foam board.
The foam board is pretty flexible but still strong.
After releasing it it went beck to being flat straight away.
The Mk3 has been made 5mm biger to give it a better profile edge where it joins the OE LCR splitter back towards the wheel arch.

This might take a while to finish but the whole splitter will be wrapped in Carbon Fibre but all the edges fully cover and sealed to make it water tight
