hay im a valitor for honda i washed my integra (looking 4 glanza if you wondering why im on hear) twice i week cus it was white but i used auto smart duet im telling you its the best stuff out there and so will the 3 show cars the the other valitors own. tryed all the others and nothing comes close (can only get it if your in the trade though) but as yours is black use a lambs wool to wash it or very clean sort spunge dont go to the bottom of the bucket and use a good very clean leather and keep it clean and you should be looking mint.if you wanner go that bit more clay your car meguires do quik clay but i use 3m (as im in the trade) and that will get rid of any fall out and make it feel smooth as a babys butt!!! as for polish te-wax is good by meguires put auto glyme ultra deep shine is made just for dark colours. but both of these have a slight cut in them. so be warned. its not the polish its the amount of times you do it that ads that glossy look once all thats done seal it with karnaboo wax. hope that helps dan
