When infusion goes bad!

After many years vac-bagging and avoiding infusion I was tempted to try it after some gentle persuasion.  Freakin' awesome!  Not hard and great results.  Yay!

However, I recently made a booboo.  Infusing a 1.2m x 0.2m part; 4x200g with 6x200g in places; peel ply, mesh, bag.  I opened the inlet clamp and it seemed to stick.  A little jiggle and the resin shot through, not all the way but a good chunk was done in about 20 sec.  Bugger!  Let it flow at a more sensible rate to finish up.  I let a little more flow in on completion but as expected its pinhole-tastic on the fast bit.  Is there any contingency for things like this, ie should I have let more resin flow through or is it a once the damage is done thats it?

If there's a fix it would be good to have a list of problems and solutions.

Thanks guys Smile  Some great tips.  I am indeed using the wingnut clamps and will give these ideas a try out on the next panel.
