plastic and vinyl trim

[ShawnF350]

My trim is Grey from new.
I`m gonna clean it really well and try a few things this weekend.
I`ll take before and afters.

Old thread with new life here.
Accum: You have said that 845 is good for trim?

Yeah, I used 845 on trim for quite a while with no complaints. I generally prepped for it with KAIO.

[ShawnF350]

Well, I did everything with "Wipe New".
It looked quite a bit better.
Today I topped it with 845.
I didn`t wipe with a MF towel afterwards.
Was I supposed to.
I may be getting this 845 on all my plastic exterior now.
I`m impressed on how easy it applied.

I`ll try to get some pics tomorrow.

ShawnF350- I always buff the 845 off the trim *before* it flashes/dries, but IMO it`s one of those "if whatever you did worked OK, then OK"- type things.

No issue with it going on OK over the Wipe New, huh?

[ShawnF350]

No problems at all topping Wipe New with 845 (24 hours later).
845 on exterior trim really worked for me. The oils or whatever carries the wax really darkens the faded look.
I will see if anything needs wiping and do a second coat of 845 tonight if I`m up for it.
Definitely will follow with a MF this time.
The top of my flares are too far gone, but the bumpers and flares looking from the side now looks 90% better.
I polished out one flare area last year and it removed the rough feeling to smooth. But didn`t fix the sunned look.
I can`t wait to see how 845 holds up after rain.

I only have used it externally.

On interior parts I would take part out for sure.

Thing is internal parts don`t get near the scratches and scuffs the outside parts get.

It is also adviseable to use an adhesion promoter with the Wurth product (no primer).

Heh heh, thre`s generally no aerosol spraying of "paint-like" products in my shop..I`m crazy-paranoid about overspray getting on stuff.

BUT...I am curious:

It is also adviseable to use an adhesion promoter with the Wurth product (no primer).

What do you use for the Adhesion Promoter? Something from SEM/etc. made for interior refinishing?
