    Plastic Hood Freshening Up?

    I have a GT235 and a GX345. Both hoods can use a freshening up. I've tried just waxing other JD hoods before but didn't seem to bring the shine back. What's the best way (other than replacing) to get these looking new? Wet sanding? Is there an aggressive wax I could try? Moderator if this is in the wrong section please move. Thanks

    Pledge works well on snowmobiles. Liquid form not aerosol.

    I'd 2nd the rubbing compound recommendation. I'm no body work pro by any means by I was always told the sequence was:

    heavy sanding > light sanding > finish (wet) sanding > compounding > waxing

    If waxing isn't working, work your way backwards through the list and use the least abrasive means necessary until you get the desired reult.

    These hoods are dyed plastic. I think sanding will irreversibly damage it. I would try a lighter approach.

    Most plastic parts are injection molded. The plastic pellets are the color of the finished product and the part is the same color all the way through. You can check by scratching the surface someplace like inside the hood. Dyeing is usually used for small lot production runs where the economics of ordering the right color material doesn't make sense. Stock white pellets and dye to match the customers color.

    Sanding isn't necessary unless there are deep scratches. Meguire's makes a line of compounding products for the auto industry. Restoring paint is dangerous for the inexperienced since it is easy to burn through the paint/clear coat. You should not have that problem with molded plastic. If it is just dull, I would try first try the glaze which is the final, finishing, step. Do it by hand in an inconspicuous location to see if that is sufficient. If not, start with succeedingly coarser compounds until you get the desired result.

    Thats what I was getting at, but this is a much better explanation. Still, the fact remains that sanding in the normal manner (coarse sand, fine sand, wet sand, buff, etc) will most likely turn out horribly.
