510 442-51031 50ml Gasket Eliminator Flange Sealant,

Does what it is supposed to do.

FYI, the product I received was in a package that doesn't match the picture. OK. No big deal, but the package is 2/3 air and 1/3 sealant. Why all the wasted packaging? And...my sealant was made in India. Not the US as the description says. It even has the price printed on it in rupees! This is clearly a grey market import.

Quality item; Fast delivery; Professionally packaged; Thank you.

The product arrived from Henkel in India ahead of schedule. The tube says: "Shake well before use", so I shook and shook and no sound of movement, so I opened up the tube (it has a wide mount) and the sealant was so firm that it would not move. There did not appear to be any damage to the tube, indicating that air had gotten in. My intended use was to seal the rear and front cylinder heads on my 1/5 scale live steam locomotive, so once in place, the rear heads are a major, MAJOR task to remove should the sealant fail. I contacted Amazon who referred me to India. The Indians wanted photos of the product, so I emailed two photos of the external of the tube and two looking down the opening to the sealant inside. A few days later I received an email from India stating that as I had not sent the requested photos, they might offer a partial refund if I returned the tube. Amazon stepped in and instantly refunded the purchase price. I then ordered the Permatex equivalent from Amazon and it arrived promptly and worked as it should.

works great.
