Fair comment..
From my experience, apply SRP with a damp cloth, and keep it damp, otherwise the chalk deposits left on the cloth make it quite dry and sticky and it will drag and become hard work. Turning the cloth as it gets like this will
help. Work back and forth along the lines of the panels rather than in circular motion, to avoid making swirl marks (your yellow car shouldn't be so bad in this respect). Don't let SRP get anywhere near dark plastics, it will whiten the surface and will be almost impossible to remove (the combination of solvents and chalk affect the surface of a lot of commonly used plastics). Work on a panel at a time, buffing off when dried to a haze.
I've never used EG seriously, apart from trying a sample pack, so advice from others may be better, but in principle apply sparingly with a soft cloth, only a thin layer is required as a sealing coat, buffing off excess.
My preference is for using a claybar and suitable lubricant (quickfinish detailer) to clean the paint surface and get a clean smooth paint preparation, ready for a good wax or synthetic sealant of your choice, depending on how often you are willing to "top up" the finish. Waxes will generally need topping up every couple of months whereas some of the synthetic sealant systems will last considerably longer, the choice is down to personal preference, car colour and finish effect required.
Youll have a busy weekend ahead!
