Water/Wind Proofing Hunting Clothes?

What do yall use?
My Artic Shield suit that I bought about 10 years ago has lost the wind proof, water proof coating. I use this suit when I go to Ks. Going in a couple of weeks. Wife picked up "Camp Dry" from Academy last night. I just sprayed a spot on my work shirt and man that stuff is strong, odor wise. I don't think that smell will go away by then.
Help!!!

I use Nikwax waterproofing spray to restore the DWR finish on stuff like that, but many other brands work. All the good ones smell awful when you put them on, but it fades once dry. I usually can't notice it the next day.

Apply it and hang them outside to dry/air for a few days, since you have time.

DWR(to keep faberic from wetting out)) use nikiwax or graingers direct spray

Water proof and wind proof is via the membrane/laminate

Thanks.Where can I find this stuff??

Easiest is on line. But Cabela’s, REI, bass pro.

Ordered 2 bottles this morning. Supposed to be here Wed. Thanks
