Detailing sprays also called QD ( quick detailers ) is very essential part in car detailing , its also called LSP ( last stage product ) or jewlling your master piece without leaving finger prints and dust particals
While working on car skin like polishing, waxing static charge comes which attracts dust and tree pollen, further waxes contain natural oils which are also attracts dust so to neutralize the surface require water, now water having lots of salt and minerals which cause scratching the surface.
Detailing sprays contains lots of distil water , very small qty carnauba , polymers and some other sealing properties which are totally safe for ur all hard work on paint and even strengthen and enhance the properties of paint sealants or wax coats.
some detailer sprays are based on natural oils and some based on synthetics
Meguiars Ultimate Detailer is one of best synthetic detailer spray based on Hydrophobic Polymer technology which not only give protective shield to ur hard work even due to its hydrophobic properties make surface extreme slick and repels water like a magic
provide additional protection to finish and being water base totaly safe for even daily use to remove routine light dust and finger prints from painted surfaces.
Its polymer base so polymers always comes into full life after few hours , once u apply this detailer spray let few hours and than see how car surface reflects like mirror and slick like real silk. Its also fills the gap between 2 wash and wax seasons like if any weekend u are not in mood for proper wash and wax so just give this detailer quick wipe ( in case car surface not very dirty ) or just shampoo wash and detailer wipe will give protection shield to ur beloved car surface from dust, and harmful vu rays
Though detailer sprays wont have longer life but being synthetic , Ultimate detailer life double than other natural oils based detailer spray 
Its heavn gift for my busy life due to my work and overseas travelling so usually my cars are maintained by wash and detailer sprays
its very easy to apply
like shampoo wash car and dry it than take fresh clean and dry microfiber and give one spray to one panel and by help of folded microfiber wipe on whole panel , turn arround microfiber and give final supreme shine wipe, follow same process on whole car and here u go blingo ride in just few moments as its final look is that car is just being waxed
