Hi, First off I must state that I was very skeptical of your product, but I thought I would give it a try.  I own a 55 Chevy with the original 265 cu. in. V8 and powerglide trans.  I could not keep it from leaking transmission fluid.  If it sat for more than a day or two without being used,  it would leak a puddle.  Over the course of the winter it would leak over a quart of fluid on the floor.  After I used your Seal Lube I have to say that the leak stopped.  I could not believe it !!!!!  I tried just about everything I could think of.  My mechanic said there was nothing he could do since the car was so old and worn.   Thanks for such a wonderful product.  I am telling all my friends about Seal Lube.   Yours truly
