Spray Jacket needs re-waterproofing - any tips

Hi guys

The interior of my Hobie Spray Jacket (shoulder area & upper chest & back) is no longer waterproof - does anyone have any tips on how to re-waterproof it?

Thanks

Buy a new one. The old one is toast.

West Marine has waterproofing spray for boat soft tops.

That's not even close to being the same material. The Hobie spray tops are made from a breathable fabric that once it loses its ability to keep water out - it's done. Breathable spray tops have a relative short (3-4 year) lifespan.

I know this is a really old thread, but this information may be useful to somebody:

I do a bit of whitewater kayaking and have to periodically maintain my dry tops and splash tops. Many of these are made with GoreTex or the 'house brand' equivalent waterproof/breathable material. Maintaining and restoring the waterproofing is a 2 part process:

1 - Wash the fabric with a very light cleanser - don't use heavy detergents that are full of dyes and scents; these can clog the material up and prohibit the breathability of the fabric. A great cleanser is called Nikwax Techwash.

2 - Retreat the DWR - this is a lot like rewaxing your car --- all waterproof/breathable garments are treated at the factory with a DWR that caused the water to bead up. Over time this will fade and need to be restored. I usually redo mine once a year depending on use - often times just washing with Techwash will do the trick..but if you haven't done anything in a couple years you should redo the DWR. The same company, Nikwax, makes 2 options for you: A TX-Direct Wash-In or TX-Direct Spray. Both work fine; I use the wash-in for anything that does not have a lining.

I think you'll be quite pleased with the results!

Well amilkovits, you revived a few jackets and snow pants. Found out there are 4 major makers of DWR: Grangers, Nikwax, McNett, Trek7. There are others too, but those come up often.

At 12$/can, I'm going to test it on my oldest garment. Only 12$ to loose.
