Cat Crap with Oakley's

I just bought some Oakley Splice's and a prizm lens for them. The goggles arrived today with some standard dark grey lenses. I've applied Cat Crap to some old crowbar lenses before and they haven't fogged since. I decided to do the same with my new grey lenses. I rubbed it on the inside lens gently with my finger and then buffed it with a chamois. Then I saw in the info packet not to rub the inside of the lenses or it will fuck up the anti-fog treatment. Soo I looked up some threads and saw people freaking out because they fucked up their oakley lenses by just touching the inside. My prizm lens arrives tomorrow and I'm wondering what i should do. So my questions are,

1. Is Cat Crap something you apply to new goggles, or is it just for when the anti-fog wears out/cleaning them?

2. Did I fuck up my grey lenses?

3. Are the prizm lenses the same way?

I would only use cat crap if ur anti fog stuff gets fucked up or it wears out otherwise I wouldnt. But since you applied it it probably won't make a difference it's alright to touch the inside although I would not recommend it because you might screw it up but just never touch them when they are wet or that with definetly fuck them up. But since you put it on it probably won't hurt although you may have to reapply it every now and then if they start fogging. But I wouldn't do it in the future unless your goggles start to fog up just let them be. I would not recommend doing it to the prisms either. The big difference between the regular lenses and the prismz is just vision. The prismz are basically like a high definition lens so I would recommend not fucking with those, just let them be. But you are probably alright I've used cat crap on oakleys that the anti fog wore out on and it works well but image to reapply it but I also think that if you use cat crap to much it does mess up the lens it quality so don't put it on again unless you need too. You'll be fine for now though but again don't put them on the prismz unless they wear out
