Fawad bhai Ultimate compound and secratch x both are abbbrassive means both cut the paint / clear coat to remove imperfections like swirls. Scratches and other imperfections. Ultimate compound and scratch x both do same however scratch x is comparitivly little less abbrasive and mainly for work on effective spot however if require u can also apply on whole car . Like Ultimate compound . Secratch x break in time is also less So these products develop for Useby hands or DA polishers and not recommanded for rotary use.
Ultimate polish is glazing polish. Its having lots of natural oils Which enrich and nourish the paint and remove paint dryness . Give very very deep gloss.depth in paint. Cleanse paint . Usually polishes Use after compounds to remove compounding marks (well Ultimate compound is based on smat technology So it won't leave any compoubding swirls)
If car skin having imperfections than Use Ultimate compound than Ultimate polish and protect ur work with wax but if car paint is in good condition than u can omit compound.
Since ur car is Mashallah new So u don't need Ultimate compound and Ultimate polish. Just do clay and apply Ultimate wax.
Detailing addicts do many experiments and different waxes layring So satisfy their detailing thurst like in base apply synthetic wax like Ultimatepaste wax . Synthetic wax give longer protection and than and good reflections than topup with natural wax to give depth in paint . Deep shine and Warm waxy touch to paint.
Your car is white So just apply Ultimate wax as #26 wax is yellow wax and leave yellowish tinch in white paint So I don't recommand u to Use #26 wax on white paint.
