Heat gun gives blotchy finish and can even melt the plastic!
Makes sense now! Previous owner must have used a heat gun on the cladding as I noticed a couple of spots where the plastic looked melted and had begun to run!
I have used "Showroom New" dye. http://www.showroomnewproducts.com/
Showroom New also has an amazing cleaning solution that you apply first and which gives the dye much better penetration. They have black and gray. This also works really well on all the exterior plastics including roof spoiler and rack plus mirrors and door handles. It is not a coating or paint and therefore is not sticky, does not chip or fade and restores the original almost non existant lustre. It has been around for a long time and user feed back suggests that it still looks new after two years.:yesgray:
