    wet sand.....help pls...

    Im new to wet sand/compound/polish...BUT,...I just did a black helmet visor and painted it white..came out great..


    prepped the plastic......painted a few coats white...wet sanded....painted....w/sanded

    then clear a few coats.....w/sand....some more coats....w/sand.....compound/wax...fantastic..

    what are you using to remove the haze? First off you need a cutting compound. Two, you'll need a high speed polisher. Makita or Millwakee. Third you'll get faster results with a wool bonnet then sponge. But you gotta know what you're doing or you'll burn through pretty fast. Getting rid of haze after wet sanding by hand takes FOREVER!!! if you are good you can cut and polish with the same product at the same time.
    Also keep in mind you are working with 20+ year old paint here. Not fresh stuff like your helmet perhaps. I don't believe they used clear coat in those days on the red paint they used. I think they used enamel.

      Go to 2000 wet or even finer - maybe even 3000, & use a stiff sponge pad to reduce finger marks. Use a wheel (air or electric buffer) & it should come right out.
      But do be careful as mentioned above. ;)

        Ceeker, you are correct--the only colors that were clearcoated were the metallics. You've been wetsanding single stage enamel paint.

        I have no further advice unfortunately.

            I had some experience with wet sanding on my coupe. A power wheel made it much easier and had better results. Check my coupe project in my sig for more info. You got any pix?

              1500 is still too abrasive. w/ 2000 or 2500grit, you shouldn't see any marks once you polish it out.

                If you're doing it by hand, try some scratch remover after the rubbing compound.

                  Turtle wax should never touch an E30, period.

                  Meguires at minimum.
