Are exterior trim products becoming obsolete to the ceramic spray waxes?

**PaulMys** · 05-24-2021, 08:59 PM

Before I found AutoGeek, I used 303 for exterior trim. It looked great until it rained. Then it just streaked down the sides of the truck. (I still use 303 for interior plastic).

If the trim is in "like new" condition, get some Wolfgang Exterior Trim Sealant (WETS).

If it is starting to "grey", clean/decontaminate, apply Solution Finish, then top with WETS.

Fair question, Bob.

To be honest…I’ve never had the chance to find out since like most here I use products more often than necessary. 😉

I have several clients that I service every two months and it still looks good but not great compared to a fresh application.

I can mix up 12oz for less than $3.

Op also stated it would last through a rain.... PERL will not. If no rain PERL is a great solution. An easy month or two. It is a good looking product though...

For me, PERL goes away the first time it gets wet. I've tried it on trim and tires diluted 1:1 and straight. Similar results regardless of dilution.

My best results were with products no longer produced, but I still have on hand: Blackfire's original Trim and Tire sealant and McKee's 37 Plastic Trim Restorer.

So what's wrong with using something like Griot's 3 in 1 or Turtle Wax SNS if it is recommended to be used on plastic trim, looks good and protects?

I did not use a trim product on my ZR2. The TWHS spray coating in conjunction with their wet wax, has my trim protected and looking great. Both are meant to be used in those areas. And to be truthful, that is a big time saver!

Nothing at all, but it depends on the type of trim. For the piano black and some of the shiny/painted plastic trim any LSP would work just fine. I've found on "raw" plastic trim it doesn't look so good and the trim still fades over time. For that type of plastic I'll use a dedicated trim product.

Photo isn't clear because I took it looking through the window but this is the type of beading from the 3 in 1 on plastic trim after rain. If it was a 303 type product, it would have run off and streaked.
