it took nearly 1.5 hours as i tried this for first time. as @aramico said you can finish in 1 hour easily. Thanks for the link. I will also follow the two bucket method. Mix 10ml in 500ml water. You dont have to wet the entire car before this. Just spray the solution and use 2 micro fiber towels to clean. (#1 for wiping dirt #2 for buffing). refer to below link: @Turbothinghy : Let me know if you come across any better product. --- Double Post Merged, Sep 28, 2016 --- @aramico thanks for this suggestion. Definitely will try after proklear. Did you buy from US site? Is it genuine? You are right about using waterless wash only if its not too dirty. Surprisingly my car was super dirty (so used 1L of water) and dint expect shine of this extent. Happy with the result. If car has monsoon muck jet water wash is preferred.
