Fairly new to all this skinning business etc, all the parts ive done so far have been just skinning, I am taking on a project to do a motorbike fuel tank. would it be beneficial to vacuum bag this tank to ensure the fabric stick to all the edges and curves properly? if so, any tips for bagging would be greatly appreciated! I have a bagging kit and vacuum on its way from easy composites. thanks in advance!

Its 6 of one half a dozen the other when it comes to skinning under vacuum.  Generally avoid it wherever possible as for most cases good results can be achieved relying on the tacky basecoat and taping the fabric over any edges/undersides. 

Ignoring the tank crush issue, the main problem with vacuum bagging is keeping the vacuum level low enough to work but not crease or crimp the fabric.  Get the vacuum too high, even slightly, and you will get the fabric creased or crimped in various places which will ruin everything.
