    Default Removing RTV from Paint

    All,

    Need some advice on the best way to get residual RTV off of the paint on my
    '94 YJ.

    I had some Avalanche (now Poison Spyder) rocker guards installed back in
    '01. They came in raw metal, no paint, powder coat, etc. I pulled them off a
    few weeks ago to have them powdercoated and found to my dismay that the
    genius at Avalanche who installed only painted the outsides, and mounted
    them with raw metal against the body. Naturally the inside was severely
    rusted. Fortunately the rust didn''t eat into the body and I was able to
    clean it all up ok.

    My big problem, he also sealed the tops of the guards with thick beads of
    black RTV. I was able to gently slice the beads off of the body without
    tearing anything up, however now I have a thin residue of RTV stuck to the
    paint and I can't find any way to get it off without sanding through the
    clear and color coats. This was one of the dumbest things I've ever seen a
    supposedly top of the line shop do. Anyone got any ideas?

    I think you may be screwed - all the RTV removers I know of also strip paint
    as well....
    If you do find something that is paint friendly, I'd be really interested in
    knowing what it is.

    Thanks everyone for your feedback. So far I've got "nothing", fingers,
    erasers, old credit cards, alcohol and gasoline. Something has to work! ;-)

    It is indeed black RTV. Easy to identify anyway, but I confirmed it with the
    installers.

    my bathroom to remove the silicon caulk around the shower. I thought RTV
    was impenetrable, but this stuff did take it off. Well, sort of. It might
    have
    removed the thicker portions if I had days to wait. What I ended up doing
    was cutting away the thick stuff and then taking 000 grit nylon pads and
    scrubbing
    the RTV with this stuff. All in all I'm pretty happy with the results.
    Nasty smelling though, I had to put a fan blowing fresh air on my face to
    keep from
    breathing the fumes.>

    Good luck

    Thanks, Dean, I'll give this a try. (Need to do a bathroom this winter,
    anyway!)

    Unfortunately my problem is that it's smeared on the paint in a few visible
    areas that aren't; covered by the rocker guards. I can't scrub on it or use
    a harsh thinner for risk of damaging the paint. Frankly I think the idea
    someone had of using an eraser may be the ticket.

    Kind of weak, but did you try Kaboom or Goof Off? I've had great luck
    even getting old rubber adhesives and stuff off painted surfaces with
    those. It's cheap, too.

    Thanks, Matt, that's another idea I can try.
    I took the rocker guards off again today to get them powder coated, so I'll
    have some time this week to try & clean this RTV mess off. I looked at
    adhesive removers today, but all of the ones at Lowes would certainly remove
    paint as well.

    3M makes a wheel for taking off stickers and striping without removing the
    paint, but i'm not sure it's safe for a clear coat. Talk to someone at a
    body shop, they use these all the time. Get a real pro's opinion.
    Another option, if you are putting them back on, just leave it.

    Unfortunately he smeared the stuff above them, like he ran a finger along it
    to wipe off excess. It's stuck on there like white on rice!

    The worst thing the nitwit did was mount them unpainted on the inside. I
    pulled them off again yesterday and took 'em to the powder coater. Cleaned
    it up a bit today and I've got some rust starting on the right side of the
    tub where it lay up against the paint. I could strangle this boob! Only
    thing I know to do is to have it stripped & repainted, or maybe sand it and
    shoot it with some rust inhibiting Krylon. Arghhhh!

    "Mike Romain" >I will say again. You 'cannot' have RTV there!>

    Yes, well I appreciate your thoughts, Mike, but it's RTV. After removing the
    thick beads of the stuff, a thin skin remains stuck to the paint outside the
    sealing surface. (If it was all going to be covered by the guards I'd just
    leave it.) Scrubbing on it's not an option asn it will tear up the paint. I
    like your gasoline suggestion which I'll try next.

    > RTV 'will' come off with an old credit card as a scraper. <


    I tried this and it was marginally successful. I'll need a LOT of credit
    cards though, as the RTV bead is about 4 ft long!

    < RTV 'will' come off if you rub it enough with your finger. >

    I may not have any fingertips left when I'm done!

    <RTV 'will' dissolve in gasoline.>

    I like this idea.

    < RTV 'will' dissolve in gasket remover. >

    Wonder what the remover will do to the paint?

    < RTV 'will' come off with a plastic pot scrubber. >

    This seems to be an option, but the process will be excruciating.

    > If you hold a gasoline soaked cloth on RTV, it will turn to jelly... (as I
    > found out with the one gas tank leak I tried to fix with the stuff, let

    Which is why they say not to seal manifolds or carb base plates with RTV.

    I get the guards back from the powder coater this afternoon, so we'll wrk on
    this over the weekend & see what happens. Thanks again for all your
    suggestions.
