Sorry if this is in the wrong section, but I'm of the thinking it's a cleaning topic.
Like many others on here my beloved Tangerine Civic has suffered at the hands of the dreaded grey trim quickly turning from a nice charcoal colour, to one which looks tired and horrible and something you wouldn't associate with a 4 year old car!
So in my pursuit for a fix, finding such notables as GTechniq C4 and similar products, I came across a YouTube video showing the use of a heat gun to return the lustre to tired and faded trim.
Not having a heat gun of my own, when my mate turned up yesterday with one (for an entirely different job I will add) I just had to give it a go, so with a fresh pair of under pants I set about trying a small area first............ I soon did the rest!!!
Basically it seems are all you are doing is lightly melting the top surface of the plastic and allowing the oils etc to rise to the top once more.
I am sure there is a fine line between going too far with the heat, so take it easy if you decide to give it a go. You will start to see the difference almost straight away and then get to know exactly how far you can go to obtain the as new finish.
You will see for the pictures I used a piece of card board to act as a heat shield from the cars paint work, which is the worrying part, but keep the heat gun moving and not stationary in one spot for too long and you'll be fine.
I'll let the pictures do the talking, but all I can say is if you've been avoiding staining as I have been and colour coding due to liking the grey trim contrast against the orange (or other colour), then this trick may just be for you. The textured finish is still there, so it's like you've just brought the car.
Picture 004 shows a half & half shot of the wheel arch trim, to give you an idea of the change taking place.
I'll see if I can find the YouTube video and post it. Got it
