Review: Excellent. - Goods match the description. Fast dispatch and delivery. I recommend this seller.
Review: Great Product! - This stuff is awesome! I used it to seal a connection between my paint sprayer and a quick connect plug (both with 1/4" NPT threads). Initially, I used Rectorseal T plus 2, which I used successfully for prior projects. For some reason, I couldn't achieve an airtight seal with Rectorseal. Loctite 542, however, produced an absolutely leak-free connection. No bubbles whatsoever when I tested the connection with soapy water after one hour. Highly recommended.
