Meguiars Ultimate Compound
One of best Compound i ever used, I said best compound in sense as only one product can achive very good finish without leaving behind compounding swirls , haze or hazy finish which usually require followup with polishing to evenout.
Based on micro abrasive technology cuts fast without scratching and remove imperfections fast and easyway oxidation, blameshes, swirls, water spots from all types of paints either single stage soild paints or multi stage paints with clear coats.
In just one step you can accomplish what used to take many products.
APPLICATION.
Meguiars Ultimate Compound is specially develop for applications by hands and DA polishers
BY HANDS :
Use soft applicator foam pad or even coat applicator pad and do one section at a time with moderate pressure and than wipe residue with clean microfiber cloth, re-apply if require.
BY DA POLISHER :
Use water moist cutting pad and set polisher speed 5 to 5.5 and apply in crosssection overlaping passes.
In case imperfections are medium or lighter side than use polishing pad with same compound and clean residue with microfiber cloth.
Though Ultimate Compound alone make swirl free shiny finish but if you require wet, deep gloss and high reflections than follow up with meguiars Ultimate Polish and finishing wax as LSP.
Here is one pic i corrected paint with Portercable DA polisher , cutting pad and Ultimate compound and see how only one product made paint perfect
