Hi,
I'll be making some CF wheel arches for my Caterham shortly and would like your recommendations as to a durable (lots of travel will hit them) resin. The arches will remain unpainted and the process I will use is vacuum infusion.
Ta in advance :-)

For resin infusion I would go with our

Cheers guys. The 'protection' that I am looking for is on the Outside of the arch (oekmont spotted that). I'm not concerned for he matting getting damaged here, as I am sure the resin 'faces' the.....

Have you made an infusion, yet? Just a question, to get an idea, what might be the background of your question. There is no actual resin layer outside. Well, there is, but a really thin one, which.....

Thought so. Are you worried about spider cracks? That won't happen with woven fabric and infused parts. These defects are caused by the thick gelcoat, and the low stiffness of chopped mat reinforced...

Not worried about that at all, I'm seeking the most impact/abrasion resistant resin for infusion.

As I said, impact resistance of the resin really isn't a problem here. And when looking for abrasion resistance, the one thing to worry about is your choice of lacquer, as you almost certainly going....
