Did they do it again, discontinue a five-star product?

My tube of "Pit Crew's Choice" sealant is about gone. I LOVE this stuff, seals and waterproofs everything. All Amazon reviews give it 5 stars (never saw a product before with all five stars). However, the product is listed as "currently unavailable". Anyone know if we can still purchase this somewhere? Thank you.
