I stupidly screwed three holes in the side of my fuel tank. It is a 190l plastic tank and luckly the holes are near the top. They are only small srew holes and my intentions are to screw the same size stainless steel screws, just shorter, back into the holes using some sealant and leave them permanently there. What I would like to know is if this is a good solution and wether Sikaflex sealant would be suitable for this case? Is sikaflex resisant to petrolium? Thanks, Stupid Me
