I think that would be plenty. Another helpful trick I learned is to have your blade warm to the touch using a blow dryer worked great, the citristrip should also be above 70F, the warmer the better. I'm impatient but if you can leave it on a couple hours instead of just one it will work better.

I've also heard of mixed results, but it definitely worked fine for me. Good luck, can't wait to see the results.
