303 Aerospace protectant on sails?

Hey all,

Has anyone tried applying 303 Aerospace protectant to their Dacron sails? Would love to make them last longer here in sunny California...

I would advise against this

I know that the Aerospace 303 site says it can be used on dacron sails, but I would first talk to your sail maker for his/her take. Aerospace 303 is mostly design to be a UV blocker/water-repellent conditioner. Dacron is already pretty UV resistant.


If you liked my advice/response, give me some rep points. If you didn't......well what do you expect, it was free.

I just spoke with a sailmaker at sailrite and he gave the 303 protectant (not the fabric guard) on dacron sails a double thumbs up. Anyone else have experience with this stuff?

Re: 303 Aerospace protectant on sails?

303 Aerospace Protectant is a beautifying liquid sunscreen, the routine use of which keeps vinyl looking like new while dramatically extending its useful life. 303 contains no petrochemicals, silicone oils or petroleum distillates. 303 is not a build-up product. 303 treated surfaces dissipate heat normally.

303 is not oily or greasy and does not attract dust. In fact, 303 treated vinyl repels dust, dirt and stains, stays cleaner longer and is much easier to clean when finally soiled. Since 303 contains a tested-safe-for-vinyl cleaner and is a cleaner and protector combined, pre-cleaners and pre-cleaning usually are not required.

303 has been tested and is recommended by major vinyl and vinyl accessory manufacturers. As the leader in UV screening technology since 1980, 303 is the most powerful UV screening treatment available for vinyl, leather, rubber, gelcoat fiberglass, and most plastics. Regular use of 303 can reduce UV caused slow-fade up to 100%
Does this stuff work on decks as well? Anybody try it?

Re: 303 Aerospace protectant on sails?

Considering its other applications/uses, 303 would certainly work. Considering its cost, however, a good sail cover, perhaps treated with 303 from time to time, would be rather more cost effective and less troblesome to apply, No?

"It is not so much for its beauty that the sea makes a claim upon men's hearts, as for that subtle something, that quality of air, that emanation from the waves, that so wonderfully renews a weary spirit."
