Hello,
what is the difference between Resin Infusion Starter Kit, Vacuum Bagging Starter Kit  & Regular Prepreg Carbon Fibre Starter Kit?
I am using only wet lay up right now and was thinking about upgrading the quality of the part I was making.

The kits are for three completely different processes.

Vacuum bagging
Resin Infusion
Pre-preg

Vacuum bagging is similar to what you do now, you just stick the finished part in a vacuum bag, pull about 20% vacuum and let it cure.

Resin Infusion and pre-preg are a bit more complicated and I would recommend you watch the videos on each process here:  Online Composites Learning Area

All three processes (and wet lay) can have good cosmetic results, although you will find infusion and pre-preg are more about proper process control rather than wet lay which needs a fair bit of skill and experience to get good results.
