    Re: '84 Formula badly oxidized, need help

    Started @900 and it dried out so fast I moved it down to 600 and started wetting down the bonnet.
    and..... light to medium pressure.. Like I would normally use.
    I think I did go heavy with the 91 Michael..
    I "X'd" the polisher wool pad with 91 - that's a lot..

    That gel-coat is crying out for a compound with a heavy concentration of our polishing oils.

    See if you can find a bottle of this where you buy your Marine polishes and compounds.

    Color Restorer

    You can apply this with a wool pad on a rotary buffer and it should cut the oxidation and bring the color back.

    If you have some M80 Speed Glaze, might test that too...

    Re: '84 Formula badly oxidized, need help

    On this side (Starboard, I used Penetrol to enrich the gelcoat and waxed the right side with the new ntx wax. I left the right side alone. The upper left corner is where I pealed the tape back to see the"Real Color" of the gelcoat.
    The Penetrol is an oil based product and I don't know how it compares to the Restore from Meguiar. I did have some of the Restore but could not find it.
    At the time I did use it, I can't remember anything coming of it...
    The left section still doesn't have that "Polished" look, but it may be the best I can get out of this ole gelcoat..

    Re: '84 Formula badly oxidized, need help

    On this side (Port/Stern) I used the 91 and my Makita @ 600 rpm. I used a substantial portion of the 32oz 91. To the left of the 91 in a circular pattern I put some Penetrol. It seems that the Penetrol enriches the gelcoat but I don't still don't get the high polish that I'd like.
    Tomorrow I'll try the 91 over the Penetrol and see what that looks like.. Thankx all for listening, still open for suggestions..
    Mike, I tried the Restorer a while back with unfavorable results.
    This finish just may be "Toast"

    Frank, when I'm back in the office tomorrow I'll shoot an email to Ash Erickson - he's our resident gel coat/Marine Line guru and basically travels around the country teaching people how to clean, polish and restore gel coat finishes. Let's see what he has to say about this.

    Hey,

    Do you have any Meguiar's #3, #7 or #45 by chance? If so, take some M07 etc and apply it to a 2'x2' area and leave it sit for about 5 minutes or so. Then come back and spray a little #34 or Quik Detailer on the residue and then remove.

    Now take the rotary with a wool pad and #49 Oxidation remover. Run the rotary at ~ 1000-1400 RPM. Work that area thoroughly until the compound is a light residue and then remove. Follow again with M45 and a W-8006 Polishing Pad and top with Flagship Marine Wax.

    Let me know if that does the trick. If so, you will need to duplicate thoses steps for the whole boat.

    Tim

    Re: '84 Formula badly oxidized, need help

    OK, I just spoke to our resident gel coat expert and trainer, Ash Erickson, and his take is basically this:

    Step down to our M67 One Step Compound and give it a few passes. That should be able to get you to the level you see on the left side of your image shown below (after 3 or 4 passes remember):


    You can probably get to that appearance faster with the 3M products, but because of their composition the resulting appearance won't last long at all. In fact, a quick wipe down with something like Windex would take it back to almost your starting point! Fast results, short term duration. Probably not what you're after. M67 One Step Compound will ultimately get you there too, and the resulting finish will last longer. But Ash believes you won't get any further than what you see above simply by buffing/polishing.

    Ash said that even a heavy application of a pure polish like M07 will just get sucked into the gel coat and not really accomplish a whole lot. His initial reaction upon seeing the photos - "yeah, that gel is about as bad as it gets". Bad as that sounds, he's seen the close up of the original color underneath that tape stripe and is confident that you can achieve that color again - but only by wetsanding to remove all the dead gel on top. Of course you'd need to go back over with the rotary, but he's seen it done time and time again. Frank, you made a comment...
    The left section still doesn't have that "Polished" look, but it may be the best I can get out of this ole gelcoat
    and Ash very much agrees with that statement, unless you wetsand.

    Just a note about the M91 Power Cut Compound: even though it is our heaviest cut product for gel coat finishes, it doesn't play well with gel that is extremely dried out. Basically you're trying to work a very dry compound against a very dry surface and the combination just is not optimal. The comments Mike and Tim have been making regarding the use of pure polishes to nourish the finish and introduce some of those oils is valid, but this gel coat is just too far gone for even that to make a huge difference.

    The idea was to apply the pure polish AFTER removing the heavy oxidation.

    The idea or goal here is after compounding and removing the dead, oxidized gel-coat is to apply a pure polish and let it penetrate or as you wrote, get sucked into the gel-coat.


    If the gel-coat is not so far gone that it cannot be saved then it is the application of the pure polish after cleaning that will restore the richness of color to the original pigments used in the gel-coat and that will help to stave off future oxidation by filling in any imperfections in the gel-coat, (polyester resin), so that water cannot get into these imperfections and cause oxidation. Then of course seal the surface with a quality coating of a wax or sealant as our pure polishes are water soluble.

    You could use M45 to be technically correct, sometimes we understand that our customers might already have an automotive pure polish in their arsenal and it's perfectly okay to test one of these for the purpose of checking to see if it helps.

    Applying a pure polish after first cleaning the surface is the most you can do to try to revive a neglected gel-coat. Some people want to try anything they can to restore and preserve a neglected finish because sometimes there are no other options, or at least viable option. Just to point out, I've worked on a lot of gel-coats in my life as well as single stage paints and one thing I've learned is...

    "You don't know what you can do until you try"


    Just to note...
    Applying a pure polish after first cleaning the surface is what Meguiar's has been teaching when it comes to gel-coat finishes and single stage paints for as long as we've been making pure polishes. We always state that applying a pure polish is an "Optional Step", you don't have to do it. Our demographic customer base trends towards the type of people that want the best results from their time, money and efforts and are willing to do an optional step like applying a pure polish to gain even better results.

    Hope that helps explain it a little deeper.
