G Aamir bhai,I am super fine Alhamdulillah and weather is fantastic these days.
yep,i am using two spray waxes lately,one is maguiar's spray wax and other is california gold by mother's.Meguiar's,i have used it a lot as stand alone product and some times as a wax booster.Mother's one is using mostly as wax booster after turtle's black box but not sharp after the application of black box,i use to do it as an in between coat for two successive complete details with black box,very rarely used it as a stand alone product.
Comparison among detailer and spray wax,you know better than me:),detailers contain less amount of wax in formulation whereas spray wax is purely a wax in liquid form.
spray waxes are less dense than liquid waxes as these are sprayed through a little orifice of the nozzle on the bottle.Basically i like more spray waxes because when you do not find enough time for proper de-wax and re-wax the car in middle of a weak,you choose to damp dabbing and want to give extra protection to your previous wax coats,do it and see the extra gloss after its application.
Aamir bhai,manufacturers even recommend to use this wax as mist and wipe then buff even on light dirt but to be on safer side if i have to dust a car i use damp dabbing prior to any wiping.Its very easy to apply and whole car takes 10 minutes,spray,wipe of with a mf and buff to shine with another towel,thats it.It does not penetrate into the paint deep rather it is used for surface contaminant remover and wax booster thus does not need curing time.
I have found no side effects on trims after the use though i avoid contacting paint waxes to the trims,for trims i use mother's leather conditioner and turtle's interior care gel.
Sir all this is just a little knowledge,and answering you with only my personal experience with these products,hope i am not doing any thing wrong,Do i?
