A word of caution...
303 products are great...I've used and like them.
303 Fabric Guard is recommended by Sunbrella for retreating for water repellency.
303 Aerospace Protectant is meant for vinyl and rubber...blocks UV and provides a nice finish...but I don't believe it should be used on fabrics as it will reduce / remove the water repellant properties.
303 Fabric Guard while great for fabrics should not be used or overspray be allowed to get on vinyl windows... it will remove the plasticisers and make vinyl windows brittle and or sticky.
I am not familiar with all of the special purpose 303 products they now market..
I suspect they are basically one of the above original products.
Best advice read the labels carefully and completely before using... I have contacted them and they were very helpful with more details on best practices using their products.
