[Archive] I need Help - Weird Problem with moldlines

so.sad:

Hey guys

I have a serious Problem with repainting this model:



(as you can see it really needs to be repainted)

To introduce the Problem I need to tell you what I already did first:

I stripped the model properly, found replacements for the weapons, reassambled to model, filled all the gaps with greenstuff and undercoated the whole thing. I then started to paint the cloak.

This is when my problem started. After the first few layers a mouldline started to appear. Oddly it was not visible from all angles but only from some points of view. Turning the model slightly would make the line disappear.

I am absolutely sure that I had removed all the mouldlines properly.

Still, I stripped the model again and carefully sanded the whole area again. This time I wanted to make sure to get a really smooth surface and to achieve that I sanded the model in several steps using a higher graining each time, finishing with 1200.

The result was an absolutely smooth surface and I was sure the moldline was gone. So I undercoated it again and started to paint the cloak. After a few layers this is the result:



again, the line is not visible from all directions - I tried to show this in the photos.

Right now I am really frustrated since I don’t have an explanation for what has happened here.

Can anybody tell me how to get rid of this nasty line or explain what is happening here?

greetings

Gar Shadowfame:

Try slicing the line with knife, then polish with grain paper.

nitroglysarine:

i have had that exact problem with a large cloak on the mordheim model of nicrodecimus (that huge wizard guy)

in the end i think, i just gave in and painted him with about 4 undercoats becaue it wasn’t obscuring the detain of anything other than a plain cloak.

so my method was to layer on the black undercoats to hide the unwanted detail.

so.sad:

guys, as I explained, I already did that. The underlying surface is perfectly smooth. That’s my problem, a moldline I can deal with but a moldline on a completly smooth surface? That out of my league…

I don’t even know why it appears, I that things like this can happen on the transition betweed different materials (it’s very rare though) but since the whole miniature is made out of the same stuff… I don’t have an explanation at all.

/Edit:

the line isn’t visible after undercoating but becomes visible when I start applying paint

Loki:

it might be to do with a fault in the metal, try putting a very thin layer of green stuff over the area and try it again from there, thats the only thing i can think of that might solve the problem best of luck

snowblizz:

It might be a “groove” in the metal. I would try filling it in with greenstuff.

It happens that the moldline is only visible from a certain angle when the light forms a shadow “behind” it

Thorne:

Personaly id filll it with copydex or layers of pva glue. Usualy it would work for me after a little paitence and perseverance

Hashut’s Blessing:

It looks to me as though it’s actually a dent rather than an embossment type of mould line. ry smoothing greenstuff over the area and blend the GS into the rest of the cloak. Either way, it will resultingly make the line disappear. Alternatively, just ignore it as the painting is good and it saves time and I’m sure people won’t mention/notice it.

you've tried multiple layers of undercoats? i got rid of this exact weird problem by handpainting 4+ layers of C-Black.

The Brain:

If this is giving you that much of a hard time, you should see a therapist for a possible OCD problem. Remember it is a hobby, not a life commitment. When you are playing a game and the table is 4 feet from your eyes nobody cares if you have mold lines.

But its the principle of the thing!

AGPO:

That’s a bit harsh Brain.

Many, myself included pursue the modeling aspect of the hobby over the gaming side. Its a perfectly valid position to want your models to look as lifelike as possible and t be frustrated if you find a problem with the casting of a showpiece miniature

Grimstonefire:

I have to suggest greenstuff as well, what may be happening is that it’s actually going the opposite way to what you expect.

I.e. you file it down from one side and it looks fine, but it’s actually the other side of the line that needed filing down.  Hard to describe, but I’ve had this happen a couple of times.

Over such a large area, a thin bit of greenstuff and blending out with a wet finger should do the job. Just remember to press hard but not leave any finger prints.

Well, I'm certainly not in the need of seeing a therapist. Please remember that not everybody has the same standart when it comes to quality and that there is a difference between showcase and tabletop miniatures.

I didn't ask for help because I couldn't continue to live without solving my problem but because I am curious what could cause such thing.

I don't think you wanted to insult me but I'd like to ask you why you post if you've got nothing to say? One can post in the off-topic forum if one just wants to post for the sake of posting.

@ the rest
thank you guys, I'll try stripping the whole miniature (again) and covering the whole area with a thin layer of greenstuff. If it works I'll hand over some slaves :)

Loki:

Best of luck i hope it works this type, look forward to seeing the model finished now :slight_smile:

nitroglysarine:

i guess the other solution is to sculpt something over it, a chain or a belt of something?

Captain Crayon:

I play around with cars a bit and you can sometimes get problems like that, even with what feels like a perfectly smooth surface.

Which is why when you paint a car (that isnt brand new steel painted by a robot) you always skim the steel with bog, sand it back, prime it and sand it back again before you paint it.

The skim of bog fills any teeny tiny imperfections in the surface that would show up once you paint it.

If you reeeeeeeeally want to get rid of it completely, i would suggest stripping it back to bare metal, and skimming the cloak (the whole cloak) with bog and then sanding it down again. I reckon if you only skim the line with greenstuff you’ll end up with more lines at the edges of the greenstuff…

It will take a looooooooong time to do and be a real pain in the rear end but it should get it out.

Otherwise paint it a lighter colours. dark colours like dark blue and black always show up minor imperfections more than brighter colours.

:slight_smile:

Hashut’s Blessing:

Let us know how it turns out either way! I hope it can be solved and it certainly does seem strange. With the amount of helpful replies you’ve got, I’m sure SOMETHING should fix it. Failing that, do as nitroglysarine has suggested and place something to cover it.

Brain, please consider that, even though you may not have wished it to be, that could have sounded offencive. On top of that, only a therapist that wargames is likely to know how to help such a problem :wink: Don’t forget that this model is almost double the scale of what we play (Warhammer and 40k), so it will be far more visible than on a 28mm, even if not particularly visible whilst gaming.

Kera foehunter:

i use sandable primer over the crack/mold line and sand it down !!

do it a few time and that should work

Hey guys,

first of all thank you for all the replies and please excause me for not answering earlier. I had a busy week at university that left me little time to do anything else.

However I managed to strip the miniature again and combined some of the methods you suggested. First I used a dremel tool to carve a deepening where the “moldline” used to be. While doing so I discovered that there was an underlying airbubble (well, not really a bubble but rather a cave) close to the surface.

I do believe that this was the reason for the weird behavior since it would explain why the effect became stronger the more material I sanded away.

Anyway, I filled the deepening with putty and sanded the surface.

I hope that I will find some free time this weekend so that I can prime the model and start painting again.

thanks for the help, I’ll keep you updated on my progress :cheers
