    whats up everyone, well i was tired of looking at my ugly brown wheel wells so i decided to paint them....i bought 2 cans of dupli color rubber truck bed coating from my work (pep boys) and degreased and sanded the inner fenders untill they were clean....then sprayed them once...waited for an hour and sprayed them again.....it looked awesome! no runs, or anything.....but that only lasted for about a day!....now its peeling off. think i should wait till it all comes off and primer it? or just grab a couple more cans and coat it a few more times? any certain brands u guys use or techniques?
    thanx

    What did you degrease and sand it with? You should wash the area thoroughly with something like Dawn and then use Prep-Sol. It's a chemical body shops use before they paint a car. You wipe this stuff on in a small area and wipe it off, BEFORE IT DRIES. It will remove the remaining grease and residue. Then you should thoroughly scuff the area with a course Scotch-Brite pad until no smooth or shinny areas show. Then wash, dry and Prep-Sol again before applying paint. Also ... if you apply the paint too thick or in too many layers it will peel and flake as you described. Look out for cheap paint too. This isn't where you'll want to cut corners.

    60 grit may actually be too course unless you are using a DA (dual action sander). The Prepping chemical is a really important step though. Especially in areas where grime and grease can work its way into the grain of the metal.

    I haven't heard to much good about duplicolor. I'd go with Herculiner next round.

    Herculiner sounds nice, but what is the price difference between the Herculiner and the Duplicolor? I would like to find a good, cheap alternative too! Let me know what you decide to do on the second attempt and how it worked out.

    You can get Herculiner for $50 and then some places have a $20 rebate so they come out to $30.... I used the Duplicolor stuff on my top. So far it's ok..... I say if you are sick of the ugly brown clean out everything really well as mentioned and POR 15 it. You can get it in black and it looks good. I am going to venture that way when I can get some extra funds.... [​IMG]

    I used the Westley's rubberized undercoating and it works like a charm. It's a bout $3 a can and a whole can can do 2-4 wheelwells. It's cheap, works great and sticks.

    Well the reason I say POR 15 it is because if you are going to all the trouble to prime it up to use the rubberized stuff then just do this instead. This will keep the rust from forming which is a better investment in the long run if you ask me.....

    Ha ha yeah I hear that... I never wash it. I sometimes wipe it down with a wet towel and touch up the rattle can job but as far as using soap, not in over 2 years...! [​IMG]
