Review: Great stuff - I have used this for it’s cushioning effect in a worn manual gearbox. It has smoothed out the gear changes and made changing gear more precise. It is only a stopgap but is working fine.
Review: This stuff really does work - I bought this product from desertcart to try to stop an oil leak coming from the gearbox on my 2006 Ford Connect 1.8TD van. It was an annoying leak that seemed to be coming from around the bell housing area. I’ve recently had a look and it is now bone dry! result!! I’m very pleased indeed.
