How to use Vallejo Putty

[kopterdoctor 110]

 

I thought this would be a little helpful tip.

I sure didn't know this.

I would like to see more shots of filled parts once they had got a coat of primer. My experience is, that's when you can tell if the filler is right or not*

 

It's an interesting product

*If you are really unlucky, after a couple of layers of top coat

i had terrible shrinkage using it, will watch the vid to see if it was user error

You have to use it in the smallest amounts possible to avoid this. It's also not particularly strong compared to many other fillers, so you can't really use it for larger gaps anyway. I find it great for hairline cracks and gaps (like those shown in the video thumbnail above), where you can smear it in, and then remove the excess with a moistened cotton bud.

is that the same stuff as "perfct plastic putty"?

It's very similar, but I prefer PPP - it seems to have a less grainy consistency, and is a little easier to work with.

If you're not a fan of Perfect Plastic Putty, you probably won't like the Vallejo stuff either.

In the typewriter years, modellers used TIPP-EX correction fluid to fill small cracks on models. The Vallejo Putty and PPP are basically the same stuff re-directed to the modelling market.

The filled seams look good when new but the putty crumbles with time.

i use PPP all the time to fill seams and cracks. with (car) primer on top i have yet to have something crack or crumble

I'm just speaking from my experience. Of course YMMV

I think these reasons are just some of the reasons I've never trusted air-dry type putty filler for anything other than a whisper of a crack. I much prefer CA mixed with a portion of Micro-balloons (some sub talc, but I find the MB easier to work with and highly controllable and sandable) as it makes for a stable base to re-scribe on, and unlike pure CA, its not harder than the surrounding plastic, therefor sands at about the same rate depending on what you are doing, and how much of the MB are added.

[blackbetty 4,125]

yeah, scribing is another story

Like others have said, I find the putty useful for filling tiny gaps and cracks.  It certainly is not as tough as two part epoxy type fillers, but does work well when used for really small jobs.  The tube tip makes it easy to apply accurately and allows one to reach tough locations such as a wheel well corner or edge so that is an advantage.  The video shows a couple of good uses for the putty like filling the tiny gap where fins join the fuselage or bomb body.

if you wipe it off wet with a q-tip you may not have to sand it at all
