what is best method to remove the sticky/tacky feel on buttons in a 458
There are a couple excellent companies that refinish the buttons, dials , etc to a better than new standard. Nothing else has the permanence or quality.
Rubbing alcohol which remove the sticky gunk. That's only a stop-gap resolution; you should still get the buttons, etc., refinished.
If going with DIY, use 90%+ isopropyl + terrycloth towel + fingernails as this will easily remove the "sticky". Note that it also removes any white labeling from plastic bits as well as the paint on ashtray cover and door handles.
As stated above by Graz There is no one better I had every plastic piece in my 430 refinished by StickyRX and the results were flawless
The results you will get from Sticky Rx are better than flawless and better than new. The finish besides flawless is PERMANENT. You wouldbe hard pressed to scratch the coating with a screwdriver. Dave let me try and using a screw driver and medium pressure I could not make a mark on a finished piece.
After having had the sticky stuff in my 430 re-done by StickyRx, their work is first rate and the way the switch gear et al should have been finished in the first place.
Robbie at http://www.stickynomore.com does a flawless job, plus he does all the parts for every Ferrari dealer. Not to mention he is a forum sponsor.
Their work is good but not at same level as stickyrx. Ive used both over since they both came to market. Stickynomore also uses stickers which is subpar to me. Plenty of dealers use rx.
My 15 Cali T just came back from the shop ... and the reverse button was bubbled. Wasn’t like that before ... I’ve never had this issue with this car (5k miles) my previous Cali (10k miles) or my first F430. Makes me wonder how much body chemistry has to do with it. The R button was the only button they were likely to have touched as there was no test drive involved. I have a guitar shop, and have seen guys who have corrosive body chemistry — one guy can absolutely trash a set of strings in 20 minutes; I can play 10 3-hour shows on my stage guitar and the strings look brand new. Curious if just a touch or two from someone with particularly acidic sweat or maybe a trace of a solvent or chemical on their hand/glove can kick off the process which then gets worse from there. I cleaned it off with alcohol and it’s just one button, so no big deal. Even the R survived. But from seeing the attention to detail from StickyRX, I would use his services. I’m also an art director who is semi obsessive about typography, and the laser etching he does of the factory lettering on even complicated parts — climate control, for example — is just spot-on.
I'm sure body chemistry is as involved as spray cleaners. My dealer published a virus policy where they will sanitize all hard touch surfaces in the interior. That's a big no in my book.
