First buyer in india, amazing product and various application
I think i am first one to buy this product on amzon in india xD. This product i have used in assembling of ktm duke 390 engine, mainly sealing crankcase seperations, it has 30 min of cure time as it says, it is semi fluid in form, but when cures up it becomes rubber type, is greatly elastic in nature, lets see this loctite can bear high temp of engine or not. Thanks amazon and popatlal.
