    Any fixes on how to get these bubbles out?

    Thanks for any thoughts.

    Probably not, it got too hot.

    Quoted from MeNaCeFiRe:

    And I don’t see the bubbles

    See picture with them outlined.

    The ramp got to hot. Unfortunately I don't know if the bubbles will be possible to remove.

    nope, you're screwed once that happens.

    Sorry thats toast now sadly. Flame polishing is a tricky process. If done correctly the result is excellent. For me, after Extreme cleaning just use Very light sweeps of heat while holding your hand on the back of the ramp. If you feel the back side getting warm you are almost to far. Very slowly done this can be great. To fast and you have bubbly melted ramps.

    This is your educational fail. You had the flame too close or lingered too long on the area. Once you bubble, it's nothing but trouble. You can't go back.

    Long fluid movements with the flame 3" or so away is the way to go. NEVER stop moving, and never get too close or heat an area for too long (which will deform the ramp).

    Some info about flame polishing here: https://www.flippers.be/flame_polishing.html

    I had this too and with 2000 grit sandpaper (and then novus or another polishing product) you can remove the bubbles.
    Don't try to flamepolish it again it will almost instantly create more bubbles.

    If the plastic is melted out of shape (but not bubbled) then you can gently put it back in the correct shape

    Thanks everyone for the help. Eric, it’s Indiana Jones.

    You can't spend too much time in one spot. You have to move quickly while holding the ramp at the right angle. As soon as you see it start to clear just a little move away to a different spot and then come back later. Work areas a little at a time. You can't rush polishing. It takes time and patience to keep from melting the ramp. The bubbles are from basically boiling the ramp and aren't going to come out.

    best to never flame polish a ramp that you can't get a replacement for brand new somewhere. and never run a flame over a crack or hole, it will open it right up.

    This is great advice often learned the hard way. Speaking from my own experience, of course. Almost considered purchasing another game to get the unobtanium ramp, then parting it out, just to finish my restoration. Great news for me, another fellow Pinsider stepped up and answered my "wanted ad".

    It also helps if you can practice first. Before I did my WWater ramps (that came out sweet) I practiced on an old ramp I had laying around.

    It's like magic when it works.
