i have a carbon fiber tank cover which i need to make a carbon bottom for the cover to turn the whole thing into a working petrol tank. i have the genuine moulds which are made from carbon including a bottom. i have a resin infusion kit plus bagging kit. so my first question is whats best kit to use for this job also i need to bond the bottom onto the tank remember there will be petrol inside so i will get some tank sealer but need to know of best bonder  for the job and where to buy. next question is once this is all together i gather the engine will get hot and maybe make the bottom of tank go soft so i need to post cure it and need to know best/easiest way to do this as i dont want petrol dripping onto a hot engine so heat stages and times will be appreciated . i do not have an oven but if i have to i will make one..lastly i need to know exact epoxy resin / hardener ratio as i seem slightly out and it takes a long time to go off or stays tacky..thank you for your time in advance
