μερικές χρήσιμες συμβουλές από τον Rinaldi, με αφορμή σχόλιο ότι τα φίλτρα ξεκόλλησαν τις ενώσεις μοντέλου
My guess is the product sat in the joints way too long because too much was applied over a gloss surface pooling in the joints....I've never been a fan of this method for just this reason. A filter is intended as a tint to the base color and not as a wash. When applied over a gloss surface such as you've described with a Future coat it just ran into all the corners and joints just like a wash, and the smaller joints not covered with enough paint and primer lost out. Page 82 of FAQ mentions it is best used over a "slightly matte surface", which helps to diffuse the product allowing for the correct tinting to occur.
In my opinion, too much faith is put into the use of Future as a be-all product for modeling. Since it was never made to endure such chemical abuse it will typically fail if not properly accounted for. Outside of glossing for decals, I think it is best to avoid as a true barrier type product.
Some of these common problems can be avoided altogether:
1) Quantity - less is more, I'm not a big fan of covering the entire model in enamel-based product, nor letting the product sit for too long. Try a smaller brush like a #2 round instead, and apply less product at one time in a more controlled manner.
2) Try speed drying with a hair dryer on low heat. This will kick off and evaporate the thinner much faster, leaving less time for it to eat away at things. I do this all the time and does help a lot for filters, washes and oils.
3) Enamel-based products work best over a primed surface and acrylic paints, but it is well known enamel-based thinners/paints/filters will destroy glue joints, especially on glued plastic link tracks. See #1.
4) Always prime -- cheap insurance. Some don't, but if you pursue these techniques and others of similar style it is always a good idea. To put it another way, I've never had a problem because I primed a model, but I have when I didn't.
5) Try airbrushing filters on as well. There is a post below by Iain Hamilton illustrating such a technique for a unique special effect, but the principle is the same when applying an overall filter in such a manner.
6) Regardless of application technique, filtering is best applied over a matte or satin finish and not a glossy one.
Fortunately the model can still be saved, good luck with it. Any further issues, please ask and I'm sure the forums will give you the needed answer.
HTH,
Mike
