One advantage to infusion is that you layout the cloth dry, so you really see what you have, the disadvantage is that it is expensive. The next step up is RTM molding this requires a two sided sealed mold much like the compression process only the resin is injected..This is typ how high end ornate production composites are made. Alu or steel tools.
There is nothing wrong with a vacuum assist layup, its time consuming and expensive, then requires secondary ops to finish the part. Its still the way 90% of composite aircraft parts are made, only they use prepreg and dont care about the finish.
thanks for that, I dont feel too bad then that I just get a few small bubbles around the edges
can you suggest a better mold release than mguires carnuba ? it releases the part well but seems to interact with the surface of the epoxy,

any of the carnuba waxes should work well. Believe it or not for a very large unmentioned aircraft company the norm was treewax sold for doing wood floors. I still use it if I'm in a pinch.
I often use freekote, but that requires an oven.
what kind of reaction are you getting? Did you seal the mold surface?

I originally planned to make only one so i didnt even do a gelcoat
it seems like the mold always needs a few runs to get conditioned , even after 5 coats and melting a few coats in with a hairdryer
if I use PVA it is really hard to release but the surface is more clear, the wax works great but leaves a dull finish that requires wetsanding with 600 and 1000 grit.
so I guess it doesnt get any better

It does sound like a mold issue. Using pva is giving you a seal and making a better part. PVA has its own issues and is problematic for most. I think your doing fine..

Got a chance to use mine yesterday, excellent at highway speeds and better visibility off road.
Looks good on the bike as well, I never liked the look of cut down standard shields.
