Hi all.

I am having some trouble with the covering of a complex part.  (Automotive gear lever surround) 
The CF Fabric is not responding well to the contours and hole in the center.  Lifting with resin etc etc....

I have tried a quick method using vacuum bagging material and the pump ...  It seems to be ok so far..but  haven't seen much info on doing things this way. 

Just curious to know if anyone else has tried this.

Im still testing the best way to adapt the fabric to the part ...but it seems like a possible shortcut to covering complex parts  

• Cover the part in CF Fabric 
• Cover part with Resin
• Cover wet part with peel ply 
• Set in bag and apply vacuum.
• After part has dried ... sand the marks from the peelply using thin sandpaper....
• Apply normal layers of resin as finishing coats.

The peel ply will leave a texture finish which iv found helps grip next coat,  I still sand just to be sure also means bag can be reused.
I tack spray the cloth to the piece,  wet the fabric ,  apply peel ply then vac bag.
Iv started to use poly resin as it' much quicker wit the extra work with the vac bagging plus parts and cured in 2mins XD

Yes, ... If more resin will be used I often sand it down with thin sand paper because if the texture is left , small dots can be seen from the layers above.

If more carbon is to be used, i think the texture is great for the next layers to grip.

I am still using epoxy and experimenting ...but it helps a lot with tight curves and nasty angles that the CF does not want to contour.
