Properties to Consider in the pursuit of the best waterproof spray.
Waterproofing sprays are like spray paint, they cover the top of whatever you apply it to. Additionally, they are a chemical cocktail of Silicone, PTFE, or Fluorochemical Urethane.
When sprayed onto fabric, they fill all the pores and gaps that would let water seep through but don’t seal the fabric entirely. Some formulations allow fabric to maintain its light feel and breath-ability but may not last.
Consequently, most fabric sprays trade off durability and safety for convenience. Culminating in a re-application about once a year depending on how often you use your rain gear. Regardless, an aerosol can of waterproofing is much less than a new Barbour jacket. But wait, there are other contenders.
