The brand's origin story began when founder Constant A. Benoit Sr. developed a shellac for bonding bicycle tires, then revolutionized automotive repair by creating an experimental gasket cement that helped a race car complete a grueling 24-hour endurance event without further head gasket failures. That spirit of innovation in demanding conditions has defined Permatex ever since.</p> <h3>A Legacy Built on Racing Performance</h3> <p>Permatex became one of the early leaders in using professional auto racing to prove product performance and promote sales.

Found radiator part # needed on Google search, Autoplicity website showed in stock. A little leery after reading some computer feedback of company, but received item in original factory packing after 4 business days, free shipping, at lowest price found. Very satisfied. This was a 'hard to find' part at a competitive pricepoint, and Autoplicity 'live-inventory' showed actual number available. Will do business with them in the future.

I was unaware that I Needed to order separate boxes for my utility rack but the second box is on the way and the price is still the best I could find.

great fast ordering

Part was an exact plug in light socket with connector wires, it snapped in place worked like a charm, they beat the expected delivery schedule, couldn't ask for anything else.

Fast and easy shopping.

It's was perfect

Seamless , and on time

It was shipped very fast and just as ordered.

I ordered a set of inner tie rods for my car from Autoplicity and found their prices to be the lowest online for the brand I was looking for. Items were ship out in 2 business days from the original manufacturer. Shipping prices were kind of on the expensive end considering the package size and weight so if Autoplicity adjust their shipping prices to be more competitive, I think their service and pricing would be hard to beat!

I love your variety

I was very pleased with my transaction with Autoplicity. My order was shipped the next day and received the following day. The pricing was also the best I could find. I would definitely buy from them again and recommend them to others.

very prompt service,items were in stock and shipped next day,salesman was helpful and friendly.Will place in favorites and do buisness with again.

Lowest prices, free and fast shipping, excellent product.

I'll start off saying that Autoplicity's prices are unbeatable...but, I placed my order on a Saturday night (which I know is the weekend)on a in stock part and it took them till the following Thursday to ship it out. I use my truck to make a living and was hoping to get it a little quicker, but now I'm down another 3-4 days till the part gets here. Also, I sent a e-mail on Tuesday evening regaurding my order and never got a response.
