What's a decent product to make the black plastic parts on the multistrada look good again, mine seems to have got white stuff like polish or it could be the silicone spray I wipe over them.
A non wax furniture polish such as Pledge is great for cleaning and a good finish to plastics ;-) For longer term finish and protection I've used Armor All for donkey's years...choice of original, gloss, Matt etc. http://www.armorall.com/products/protectants/original-protectant More recently I've started using 303 Aerospace Protectant as well / instead after recommendations.....cant find the manufacturers website, just Google... 303 Aerospace Protectant
I use this regularly...it’s really good for removing grime and polish residue and smells nice too https://www.google.co.uk/search?q=M...+Cle&ie=UTF-8&oe=UTF-8&hl=en-gb&client=safari
it's a controversial one as a lot of cleaning and "preserving" sprays permeate plastic and so will end up "in it" rather than "on it". If the change isn't detrimental to surface appearance then I guess it's all good.
Okkidoki.....wipe down first all plastic parts with IPA alcohol ( This will promote adhesion )....then for the recolour back to factory fresh use Solution Finish....this stuff is AMAZING...no other and I mean no other product available comes close... https://www.cleanyourcar.co.uk/solution-finish-black-trim-restorer My work is done... ps. you only need the tiny bottle....a little goes a looooooooong way
Gtechniq C4..... you will need to clean all the old products off the plastic first then apply a few drops on an application pad... you cant go wrong with Gtechniq....
