Blue Tac Sausages and Cammo


Recommended Posts

I have heard of this method and seen it used by a couple guys on here now. It usually involves laying down your blue tac sausages along the lines of demarcation and then either filling in the inside with liquid mask or with masking tape.

My question is this; does this technique achieve that feathered edge? I have heard of people using blue tac to lift a paper mask off the surface and then giving the model an edge but I didn't know if this worked the same.

I am guessing it does not but the technique looks to be pretty good as far as other planes who do not have these soft feathered edges.

Yup that is does ...

Here's an Osprey I have just finished, first in bluetac/blue tape then the finished product.

I prefer this way to have control and achieve soft edges in all places. More distance from paper to surface makes more softer edges.

But in my previous experience using directly Blue Tac, some places shows hard edges while others were soft depending the angle of your AB.

Very true!

To keep the soft edge, be sure of the angle the paint is hitting the blue tak. Spraying downwards or straight on will give you the soft edge. Shooting upwards will guarantee a hard edge.

It worked for me with a narrower band of blue tak and taking my time. Great effect.

Yes,

the angle of your AB determines how much feathering you get, in 1.72 I try and keep it tight.

I built this RF-101 to test this method and I was very pleased with the results;

One thing I did learn was not to put the blutac on matt paint as it left a faint grease mark, you can just see this on the tan, it was not really visable on the green.

Forgot to mention that!

Yes - blue has a residue. I use white tak and it has none of those issues.

Funny, I use blue blu tack and don't have that problem. Maybe its a different formula or something.

Anyway, here are some of my efforts using it. I like the technique, simple and effective, if a little time consuming!

Another factor to the residue issue, is how old is you blu-tac? I have been using the same piece since 2003 and occasionally add some new to replenish, and never had any residue issues. On one of my recent builds, I had some holding a canopy over a matt black cockpit for over a year, and no issues.

Hi all,

I use Silly Putty in the little red egg. NEVER an issue with oils and really easy to work with. You can buy it at most toy stores, Wal-Mart etc. for next to nothing, and it never dries out.

Cheers
