Topic: Decal Set problem.
Replies: 5
Views: 2490

As Phule said Solvaset is pretty caustic as a decal set goes. I use it only on thick decals. It'll ruin many of the new very thin decals. Go with the Microset system the micro sol softens the decal and the set gets the decal to lay down and conform to the surface.

Cheers,

For filling I almost exclusively use epoxy putty. When I do use a seam filler I use the bondo finishing putty as it is a lot cheaper than the model stuff and better IMHO. I do wet sand exclusively and you will find that it creates a finer more "polished" surface when you are done. Cheers, ...

I agree Oils or pastels are the way to go.
Also, I have used a post-it-note snuggled up against a scribed line to make it look like it leached from the seam.

How fine a sand paper did use to finish the piece? You should work progressively up to 6000 grit and always use a wet sanding technique.

When I am brushing with Acrylic in any of my Paasches I typically I clean with Windex. I also keep an airbrush bottle full of Windex to run through the brush from time to time. It helps to keep it cleaner and makes for less final clean up..

Generally the "milk" consistancy is correct. With Model Master paints as a rule you only need to add about one quatrer thinner to 3/4 paint. Most others I go 2:1 paint/ thinner.

I think the 2 ton epoxy might be your best bet as you are not likely to get any warping of fthe styrene (provided the gaps in your frame work are not too big).

I would say contact cement if you are not concerned with the longevity of the model. The problem with most contact cements is that they can be affected by heat, humidity, etc. If you use a "hardcore" contact cements like those used in the flooring industry are not likely to be effected the...

Personally i only use the Bondo glazing putty as a spot filler. I much prefer using Aves Expoxy Scult or Magic Sculpt epoxy putties for the vast majoriity of my filling requirements. This and smooth them with alcohol and you are ready to go.

Thanks for the heating tip Jack. I forgot to mention that heat can speed the cure time. Just so you all know, if you are working on a metal or white metal kit, 20 min in the oven on warm (125-150 degrees) will cure the putty and not effect the metal.

I have also found that the Alcohol dries faster than the saftey solvent. Thus keeping the putty from getting to "gooy". That is one of the reasons I never use water.

You may want to hit an autoparts store and pick up some Bondo glazing putty. It is a main stay for spot filling, sands easily and is cheap for the ammount you get (much cheaper than Squadren Green stuff).

One of the things you need to consider when using Sculpy and Super Sculpy is that they are oil based polymers. Baking at 125 for 15 minutes will not cure the sculpy and you will have the residual oil to deal with. When I sculpt in super sculpy I generally bake it at 200-225 for a couple of hours. Th...

Two factors figure in with Milliput age and mixing ratio. It is very unforgiving if not mixed almost exactly 50/50. Also if it is over a year old it could be going bad which will effect it's ability to cure completely.
