I have a new car and have no visible swirls a few hairline scratches that have to be seen under the right light and the right angle, I can live with them.. so I am looking for a very gentle pre-wax paint cleanser not trying to remove any paint or clear coat only trying to clean the paint after claying so I can apply LSP which will be OPT Opti-Seal ( due to my skill level I will be doing the work by hand I never used a machine and dont own one and time constraints I need products that are easy to use and easy to apply. I have been spending weeks reading previous threads and other useful info online and the most popular gentle products seem to be Klasse AIO and P21S GEPC and Sonus paintwork cleanser. I have used KAIO and like that it leaves no dust and you can apply it and dont need to let it haze you can just wipe it off but what I dont like is that it leaves protection behing I just want to apply the LSP Opti-seal with no product under it. P21S GEPC I have read this is very gentle and provides great results but that it leaves oils behind and is more suitable for a nuba as a LSP topper. Sonus PC is the one I am looking to order its very gentle and cleans and has a very fine polish without leaving any protection but my question for those who know is.. is it as easy to apply as KAIO where it does not dust and does not need to haze making it easy to buff off right after applying and spreading it???
