In anticipation of applying R/R, I went almost 3 months with no treatment of any kind on my cladding (and nothing from the car wash), actually got a tad faded out looking. Even recall somebody in Moab 2009 telling me to treat my cladding as it was so dry looking! I prepped with washing after washing, then even used Windex and 409 (I think). Really don't "think" the front cladding was prepped in any different fashion, but I agree, mav, that could be a possibility. My can could also have some contamination or something different in the batch. Guess we'll never know. But I'm really glad to hear it's working so well for some.

Know the label said it actually penetrates the plastic, but I can't say that I "saw" that, or could really say one way or the other. I do know it formed a nice hard satin finish that never washed off or deteriorated in any way. About a year later, I decided to add a 2nd coat cuz I read the instructions and it said you can do that, and I thought it would be a good, final step.

When I did the 2nd coat, it seemed to me to be much shinier, which I didn't like, but oh well, it's permanent.

John, you're using One Grand ERV....did you find a way to remove the R/R, or does that stuff successfully go on top of R/R? I've even thought of using some super fine sandpaper and just ever so lightly sanding everything, hoping it would open up some pores, that I could then soak with 303 or the TS-1.

Boy, my 1st choice would be to "remove" the R/R if I could.....then try the TS-1 or 303. I'm now with you John, wiping it down with something frequently would not be a problem, now that I know what I know.
