    Feb 10, 2011, 6:29 PM - Need some help on my Jetpack #1

    I'm starting to test fit all the JP pieces before I prime and attempt to paint this thing. It's a MOW pack and I have 3 questions:

    1. Some parts have seams on them from the casting process, do you guys sand these seams down or leave them be?

    2. Some parts have little chips. I'll probably leave some of them like the one on the thruster below (pic also shows a seam), but for other chips what can I use to fill them and then smooth it out? Will just a spot filler work? Any recommendations on what to get?



    3. One or two parts have little bubbles. Again, I'm guessing a spot filler will take care of these?


    Thanks!

    I, and so do most others on here, sand the seam line out. Before you go filling in any holes I would recommend giving it a coat of primer, the primer will then better show any flaws, chips and pin holing that you need to fix with filler. Once done, do the appropriate sanding and wet sanding, then hit it with another coat of primer so your ready to start painting.
    The second pic you posted is known as pin holing, I had alot of these on my old gauntlets and they are a nuisance to fill IMHO. What I did was using a latex glove, pushed and spread the filler over the area to make sure it went in the holes. You could also try filler primer which will fill up most of the smaller holes.

    I agree with the above post.

    I am working on a MOW arena pack and had several of the same issues. I sanded, wet sanded, primed, filled with bondo....repeat. The primer really will show you the flaws.

    Thanks for the tips guys, primer first is a good idea. Any recommendation for what filler to buy? I haven't worked with a filler or Bondo before but I think I read on here about a spot filler in a black and red tube? I'll be running by Walmart if they have something I can use.

    I used the spot filler from Bondo. It comes in a red and black tube. The spot filler works well on small things but it is not made to go over large spots or large coverage. The spot filler will work fine on the small air holw type bubbles that you have though. It is easy to use. Make sure you work it into the holes though. you don't want to just smear it over the surface and then sand it off with the holes still there. And yes that is from expierence.

    Bondo is easier to work with than you might think but it is kinda intimidating the first time. There is something about mixing an item and the clock starts ticking that makes me nervous.

    Okay, so Bondo brand spot filler. I'll try it on some spare plastic first to get a feel for it, thanks
