this product has proved itself to be quite good, fully cured on a little gentle midnight trip to tesco last night!
unfortunatly theres no noticeable change in performance.
but i reckon it has sealed the crack
would reccomend as i have loads of the stuff left still for various other jobs
so good value for money really!
i'm hoping it will pass MOT with it on there, might heat wrap around it and cover up
hoping heat wrap will improve perf. too
any questions/thought/advice appreciated as always
