    Question Cleaning Before Painting.

    IMG_1073.JPG
    Alright. I need to ask.
    I've found a bunch of different methods.

    People wash on runners.

    After they clip, and with soap and alcohol.

    Some say modern kits don't need it.

    Some like Funkatown use a ultrasonic cleaner.

    Whats going on here? There's so much up in the air with this topic.

    Does Bandai Really use a special lubricant on their plastic for the molds that can interfere with the painting process?

    Is there
    1. A older modeling resource for plamo kits that discusses this.
    2.Is there a physical resource in japanese that discusses this topic?

    I personally have decided a Ultrasonic Cleaner would be a sound investment.
    Also i can clean my glasses and more with it.

    So far I'm sticking to using soap and water and scrubbing with a toothbrush.

    I'd really just like to know more to clear this topic up. Thank you so much guys!

    Re: Cleaning Before Painting.

    It all depends if you're going to do any masking. If you are trying to paint multiple color on the same piece, you would paint the whole piece in the lighter color then use tape to mask it off then paint the darker color. In cases like that. If you do not clean the surface properly. There is a chance that you may peel off some paint when you remove the masking tape. I use basic dish washing soap (make sure it doesn't have any moisturizer or other additives) and water. rinse then air dry.

    Ultrasonic cleaners are also handy for cleaning airbrush parts.

    Re: Cleaning Before Painting.

    A confusing topic, indeed. When I first got back into gunpla, I'd wash parts directly on the tree, which was a total pain in the ass. Now though, I wait until all the nubs have been sanded off before I wash the parts in a small bowl (with a lid) of plain warm water and dish soap. To be honest, I'm not even completely sure any washing is necessary these days because the kit technology is so good; if working with an older kit however, washing the parts is probably a good idea. Though, if you're like my dad, whose been building models since he was a kid, he thinks the whole washing parts debate is BS, lol. In short, you can only go by what works for you.

    yah that happened to me before. Normally I just run the masking tape over some cloth or the surface of my skin to make it less sticky before masking.

    Re: Cleaning Before Painting.

    When I was working my TGIII, I tried the 90% ISO alcohol method of cleaning parts to prepare them for priming. Nothing fancy, just got some on a lint-free cloth and wiped at the surfaces to be painted. Seemed to work really well with letting a primer coat stick, at least when compared to previous method of washing with dish soap and water and letting them air dry.

    Re: Cleaning Before Painting.

    Awesome guys! Thanks. I think I won't worry about it then. Unless I do eventually get a ultrasonic cleaner.
    I'd love to get one of those though. for cleaning all sorts of things.
    I appreciate the feddback.

    May have to give that a try as soap washing have it's problem too if you do not get all the soap residue off the parts and then you have the problem of dust while it air dries.

    ^ That's exactly what happened to me a few times. The alcohol method doesn't have that problem due to how fast and how complete the stuff evaporates.

    Re: Cleaning Before Painting.

    I'll have to try that, myself. Because one thing I noticed with the dish soap method, and this may just be me, but the parts feel a bit slippery afterward, even after giving them a good rinse. How much ISO alcohol is needed, just enough so that the parts are submerged or...? Any rinsing necessary?

    Re: Cleaning Before Painting.

    Hmmm, I'd say you need just enough as if you're going to rub it to sterilize something. What I do is just cover the alcohol bottle opening with the cloth and invert the bottle quickly, which gets enough on to be used to wipe, but not enough that the cloth is soggy. I then repeat as necessary until all parts are wiped clean. You can apply with eye droppers too.

    Also, no need to submerge or rinse; Simply wipe and wait.

    Re: Cleaning Before Painting.

    You're welcome, good madam. Hopefully it gives you good results too. All thanks should be going to the person on Instagram that first mentioned it, haha. I don't remember what his name was, but his idea was a darn good one.
