Hello together, I know, a somewhat strange question, but for good reason: I always use the Chemical Guys Natural Shine Dressing for my BMW E36 for plastic care outside (ceilings, diffuser hood, window seals, rear-view mirrors – unpainted plastic). I’m also quite satisfied with it overall, only in the rain it doesn’t last quite long. Now a little misadventure has happened to me recently: I have maintained the unpainted plastic in the mirrors, and instead of The Chemical Guy’s Natural Shine Dressing uses the Chemical Guy’s Jet Seal 109 (Paint Sealing). Don’t ask me why, but it was an extremely hot and exhausting day, and the bottles were standing side by side (they look similar as well…). Anyway, I panicked that the plastic might not react so well and I ruined everything. I’ll be over it again with the MFT, but the seal was already completely in the plastic “eared up anyway”. The look is great (beautiful “original”, not as shiny as with the Natural Shine Dressing) and while other plastic parts are already screaming for care again, the mirrors still look as if they have just been made fresh. You also see that water is pearling very well. Now I wonder if varnish seal on plastic is an inside tip or yet a no-go? How can it behave on rough plastic (e.g. the bumpers) i I don’t dare to use it there, I’m afraid that the sealing in the bumps is too hard and you get a problem. A sealing should be applied thinly and then taken off again. What are your opinions/experiences on this topic?
