Very very good stuff, Used it on an old BSA motorcycle casings

A nice sealant, and being black I used to stick my old classic name emblem on and it works a treat.

Does a good job seals well easy to use. Previous review of mine was left for the wrong product.

Good value at £6.99 on Amazon with lots of good reviews. The Plextone sealant had a good amount of "grab" when I placed the valve cover onto the vertical face of the lawn mower engine and held in place with my hand until secured with the bolts. Only needed a small amount for the valve cover seal, so after use, removed the nozzle provided and replaced with the original cap, should I need the product at a later date for another task. Cleaned sealant from the nozzle supplied, with the aid of blue workshop paper, isopropyl alcohol and the shaft of an old small paint touch up brush to work the sealant out of the nozzle, so that the nozzle is available for use if required.

Good quick gasket macker

Good price and quality with fast delivery. Easy to use

Used on a cam cover, good consistency and easy to apply. So far no issues after about 500 miles. The nozzle will need cleaning each time though to use later.
