    Sanding is a real messy job

    Post by gooberdz on Mon 20 Oct 2014, 8:13 pm

    What do you do to keep things clean when you're sanding or cutting of nub marks?

    I just started practicing sanding off nub marks, and its just such a mess. I also noticed that I was breathing in a lot of dust particles while doing this. That got me rather worried and I put on my new respirator (which was meant to protect myself from inhaling the fumes from spraying top coat)

    Is there anything that you guys do to manage the dust? Do you use a mask while sanding? Is sanding with water a better solution?

    Also, what sandpaper do you use to achieve the same shine on the plastic after removing the nubs? Because my 6 sided nail file + using 1200 grit sand paper still leaves some really small visible scratches even though its been buffed and feels totally ok.

    Thanks!

    Wetsanding would address yr concern to a large extend. And cleaner for yr surrounding, less cleaning up.

    For yr concern abt the nubmarks, u might wan to refer to the tutorial by landel bro here
    Hope it helps

    get proper sand paper for wet sanding though. Buffing stick might lose most of its abrasive particles when in contact with water(at least that's what happened to mine).

    any idea where I can find it? I tried home fix but they only carry 100 -200 grit types.

    standard place to be looking for them(tamiya 400+600+1000 set) would be our local hobby shops.
    Hobby Art @ Work, Hobby Art Gallery, Hobby point.
    u can also try Artfriend.

    cut them up into smaller strips and glue onto an ice cream stick to use for most flat surface much like a file.
    Prefer to dap some water on my finger & rub it onto the abrasive surface, then drop some more on it before sanding. will only rub with water each time i see that the abrasive side is clogged with plastic particles when wet sanding.

    Thanks a lot. I'm already using 1200 grit but yet I still see scratches. Are these small scratches going to be an issue?

    Usually I only sand up till 600 grit. I start off with a metal file or 300 grit then work up to 600 wet sand. Gets the job done, no obvious deep scratches after priming.

    the problem isnt about already using 1200, it is more about the build up. u have to sand by gliding n not pure pressure with every lower grit, make sure u dont end up with deep cuts what will still end up as shallow scratches as u further sand with higher & higher grits. like celeron mention it wont be a problem if u're painting ur kit. coz the primer will patch those up. i also stop at 600 ever since i picked up modding.

    if they are just hairline scratches i dun think they will be an issue with panel line washing lah, if that's the issure u're talking about. take a spoon n sand until what u get on ur parts. then just do a wash n check if it is getting stain? if u wan its to be perfectly clear of scratches like the original plastic surface. u would really need to invest on compound to polish from coarse to fine to finish. getting compound will be overkill considering u're gonna flat coat it later.

    Thanks again. Great guide and never knew there were that many factors to sanding!

    yah seam lines appear to be easy but when there are nooks and crannies it gets pretty tough. Painting maybe not so soon I guess.

    i used to use metal files to file off the larger nub bumps. they tend to be faster but you need to be careful with your speed or you might over-sand. As for the mess, wet sanding is a better choice when it comes to cleaning up after.

    as for the seamlines, you will need to use a finer sandpaper like what the bros recommended. they are easily available at some of the more "neighbourhood" hardware stores.
