Roof made and sitting pretty

With the mould made last time I finally got round to making the roof, my main concern here is to ensure that there is enough cure time between each step and to also insure that there is enough material to make the roof strong.

This time around I made sure that I asked enough questions to make sure that I had enough core mat, glass and the correct resin and the end result is fantastic, we are all very pleased

It started out with 2 layers of gel coat to ensure that any sanding that may be needed for the roof could be done without sanding into the glass layer.



I then followed with 2 layers of 450g chop strand mat, then a full covering of 3mm core mat with extra core mat across the middle sections, then 1 layer of 650g mat and a final layer of 450g mat and then it was left for 1 week to cure.


The mould was so well waxed up with a little bit of effort the roof was released from the mould leaving a good looking roof skin and a smile on my face. We then carried the skin over to the car and placed it on the roof ready for trimming




Then with a mask on and a 3" cut off disc I carefully trimmed the roof skin down and although there is a little bit of work needed to the skin just to be sure that it is perfect




The car was then cleaned inside and we scotched the inside ready for this weeks painting event where the interior and hopefully the exterior will be painted. Then once done the roof will be bonded on (its left off to make painting inside easier) Finally the carbon skin will be added to cap the roof and then we are on to assembly. Maybe done for 2013...

Grp roof mould

Again I am back here making the mould for the roof, this time a lot of time has been put into waxing to aid with the release.
All the hard work paid off with waxing, I was able to lift the mould off with just my thumbs and very little force. When lifting the mould off it was clear that the heat of the mould had damaged the roof.



Luckily for me the mould had firmly set prior to the roof cracking...

Mould was then placed on the floor and trimmed ready for me to make the actual roof. Then that's it, no more roof saga
