Flexi-Hone 3.5”
Did a great job, really easy to use

Needed this to refresh some bores that were bored out oversized and had oiling consumption issues. I Ordered new rings and wanted to refresh the cross-hatch. as seen in first image of the bore, the machining marks are visible however the cross hatch isn't except for at the top where the crown sits and the rings don't ride on the cylinder walls. I used two Flex Hones to achieve the desired result, a somewhat course one & then a finer one for the finish. Hopefully the rings will Bedd themselves in nicely and have good oil retention. This is on a Toyota 2JZ 6 Cylinder Engine with an overbore of 86.5mm

Be careful when using this. I was sent a product that was larger than what I needed (and had ordered) and I failed to notice until it was too late.
