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 20ml/0.7oz bottle and the large 100ml/3.4oz bottle.
