Tajima Convoy Super 12 is a mastic man's mastic gun. The Auto Flow Stop feature virtually eliminates the risk of mastic leakage when the gun is not in use, so you can say goodbye to silicone stains on work clothes and no more scraping dried Flexy Fix or sealant off floors.

Engineered in Japan, using high quality materials, this mastic gun is extremely durable, so it will stand the test of time. 

The Tajima Convoy Super 12 boasts a 360 degree rotating handle and Twin Thrust 12:1 gear transmition ratio, making it one of the easiest mastic guns to work with.

Works best with sealant and adhesive cartridges of up to 310ml.

Do yourself a favour and buy one. You're worth it!
