Review Hylomar Gasket Sealant 40mL (OSGS)

By: on 28 February 2022
I was very happy with the service and all parts was correct and arrived in a reasonable time frame. Im no mechanic by any means but after a couple of YouTube vids I had a crack at it and went to test my work out. The boat motor ran like a dream. Highly recommend your business and service. Thanks a lot outboard spares

A non setting sealant can be relied on. I've used it for years without a failure. I came across the product many years ago from its prescribed use in aircraft engines. I've even successfully used it to reuse a cylinder head gasket in desperate times. (Note this use is NOT Recommended)
