What did you use to re blacken the exterior trim? In the past I've used autoglym bumper gell but it tends to run about if it rains. I've also used a sealant on my plastic trim called autobrite abyss from their hell shine range. However, I'm not sure if this restores back to colour or just protects it from going back to grey.
I've been told about the heat gun treatment,It'll be my next plan of action if this doesn't work!Heat Gun

Instantly, so exercise cautionhow long does it normally take ya to black the bumpers up using a heat gun
smooth peanut butter does the trick for me on the blacks
