Pigment fixer dissolving my model?

[Guest]

Just wondered if anyone else has come across this.

I'm using some Mig Pigments & their fixer, and where I've been a bit too generous with the liquid it's softening the glue joints and the thing is self destructing :flushed:

Obviously I need to be more careful, but is this something I should have expected? Are the solvents in it known for this?

Thanks,
Andy.

I just use thinned down acrylic varnish. Works for me and saves buying extra things you dont really need...
Never heard of propriortory fixers attacking glues before though.

Thanks Ian. Trying to give myself a fighting chance by using ready made products. Probably unnecessary like you say but I need all the help I can get! :smiling5:

A blast with the hairdryer has firmed the joints back up. Will be more wary of where I apply it now.

Totally Andy. Most of us though have some type of clear coat Acrylic of otherwise. Dont tell anyone but half the time these "special" formular this that and the other are all the same stuff.. I use varnish 'cause I have it and they (manurfacturers) have more money than I do. lol. As a bonus, gloss varnish gives a good wet mud look and matt a nice almost totally flat dried up mud look. (Put it on thick enough and dry it quick and it can even crack up like mud does) .

Yes, I'm sure there's a lot of clever marketing going on to fool people like me into buying several bottles of the same stuff with a different label! I've tried my best to avoid it up until now but knew I'd give in eventually.

Some areas will be getting gloss varnish anyway for the wet look, but I like the cracked mud idea.

Hi Andy
Some products do 'reactivate' previously used products. Decals treated with MicroSol and laying down nicely can wrinkle up again with an acrylic varnish. They will lay flat again if just left alone. Although I have not had glue soften it sounds as if your issue is similar. Paints, glues, washes etc all need longer to dry than we imagine. Rushing one process on top of another can lead to problems.
I must agree with Ian regarding some of the 'stuff' manufacturers would like us to buy. I am a real sucker for 'must have' products which the makers swear will improve my models :rolling: They sit gathering dust and I resort to basic, tried and tested methods.

Thanks for the tip. Very useful!

Hi Andy, local turps react to joints the same way as we use it to thin oil paints for panel or dirty wash. I have since stopped that process and use watercolor instead. I guess if I use artist turps it might not react the same.

Cheers,

Thanks Richard.

I tried using a pipette to apply the fixer at first but it was a bit lively to say the least and I ended up with liquid running off the model, so no doubt some seeped into the joints causing the issue. I've since switched to dabbing the fixer on with a small brush and it's much more controlled.

Now if I can just stop knocking bits off or dropping them on the floor I might actually get these models finished! :smiling5:

Yes it does Andy. I use MIG and it is quite an aggressive fixer. I tend to let one drop go along way. I use it mainy as the initial fixer then once dry I reinforce the work with extra pigments but using other fixers as already mentioned in the thread. Once that stage is complete I finish off with more pigments and oil work. All together around three layers of pigments will be added to create depth and variety.

Thanks Steve. I think one thing I definitely need to work on is layering (and my patience lol!) I'm trying to get things done in one shot so no wonder I'm not getting quite the results I'd hoped for.

Think we either all do this Andy or have done. Once your in the swing you don't want to stop, suppose it's learning to leave it alone until the next day .

I know what you mean John. My problem is that if I have to leave something until the next day I'll have nothing to do so end up starting something else and soon have too many things on the go at once. I've already built, primed and preshaded two more models whilst waiting for my resin water to arrive!

Then there's the drying time with oils. I've patiently waited up to a week for them to dry before now but as soon as I try to go over them with another layer or different effect (like an oil or enamel pin wash) it strips the previous one off. That's the kind of thing they never tell you about in the hundreds of weathering videos I've watched. There must be a way around it but I haven't found it yet so will keep practicing until I crack it :smiling3:
