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!

Vacuum bagging will certainly help in pushing the carbon into the edges and curves. However, a word of caution. I wouldn't go to a full vacuum as there is a good chance that it will deform the thin metal. Think about it, nearly 15lb of weight would be pressing down on every square inch of the tank! Just pull enough vacuum to ensure that the carbon is snug againt the tank and no more.

     As long as the tank was sealed and you werent evacuating the air from the inside of the tank, the pressure would be even on both sides of the walls and you wouldnt crush it. Should be possible to...

     If you can seal the tank then, yes, Hanaldo is correct. However, getting the cloth to adhere tightly to the fuel cap resess may be a challenge without the aid of a small vacuum. I would use a partial...

     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 tapin...

     As you can see, the tank will collapse under vacuum! 😆 And that was using a regulator at 10% too. My advise is to ensure the tank is sealed and add a vent tube to it. Sam

             If you add a vent tube the tank won't be sealed. ?

                 Well, the thing is, as much as you attempt to seal the tank, it is very difficult to get it completely air tight and in turn stopping the air from being evacuated from the inside of the tank whilst.....

                     Not with you here. If you vent the tank, you are allowing air to escape from the tank, yes? In that case there will be no contained air inside the tank to resist the vacuum pressure and it will...

     Not if you vent the tank through to the outside of the bag Steve. Then you are pulling air into the tank from outside the bag, which is essentially creating a leak in the bag but preventing the tank....
