## Customer Reviews

### ⭐⭐⭐⭐⭐ This stuff actually works
*by A***R on September 10, 2025*

I had an oil leak from my rear main seal on my 2005 E55 AMG, and figured I would try this before dropping the transmission. I can't believe it worked. I was leaking about 1 qt every 200miles, and it seemingly has restored the gasket to its original condition, as advertised. Worth the money.

### ⭐⭐⭐⭐⭐ AT 205 seal leak
*by J***E on September 20, 2025*

Have been buying AT 205 for years. Helped stop 95% of my engine oil leak on my 2010 ford focus. Great product. Will continue to buy.

### ⭐⭐⭐⭐⭐ Be patient might take two applications but should work
*by J***K on August 20, 2025*

It worked for me on my TDI Diesel Jetta injection pump that was leaking and smelled like strong diesel fuel smell. Followed the correct amount when I got down to about 6 gallons of fuel put in correct amount an let it sit overnight. Repeated twice completely fixed to puddle or smell anymore. Saved me $$$
