303® Marine Aerospace Protectant
The 303 Aerospace Protectant is a fluid made to keep rubber materials in top condition year after year, preventing the material to age due to sunlight and such.
It was first developed for NASA’s facilities where protection of hoses and other rubber details was important in Florida’s intense sunshine. We use it to keep our spring cores in great condition by applying a few drops once every few months.
We sell it in two sizes, the smaller 473ml/16oz bottle and the large 946ml/32oz bottle.
