Alfa model decal application and preservation.

One question that is asked frequently is: "How do I protect my Alfa model decals?" Well there are a number of ways, but the following links below are to a number of posts explaining what I do to the apply and protect the decals. These links are from a couple years ago in the Alfa Model Spitfire thread. Hopefully, this wil be of help and of course any questions or comments are always welcome.

All good points there Dora.

I know you mentioned it, but it can't be overstated enough that the decal must not be over-soaked. This is probably the single most common reason decals peel away from the airframe after a short time.

The decal must not be immersed for any longer then 10 seconds or all of the adhesive needed to properly adhere to the model will be washed away.

Also, when the decal and backing is removed from the water bath, it must be placed on a non-absorbent/non-porous surface to soak. If it is placed on a absorbent surface, such as a paper towel, the adhesive will soak into the towel and not stay with the decal.

Good points as well. I think next I am going to do something about the Alfa motor questions. That seems to come up equally as much.

I'm getting ready to do this on my 109. Brushing the SET on is all you need to do to be able to move the decal around on the surface? I've done it with water, but never used the SET/SOL before.

I've also read about people spraying a gloss clearcoat down before they apply decals to prevent silvering. You don't need to do that using the SET, correct?

Adding a layer of gloss prior to the decals is fine. It certainly WILL help. However, you MUST make sure it's 100% dry prior to decaling. I would wait atleast over night. The decal setting solutions are both a mild acid, and could damage the finish of the gloss cote.

When I do the decaling, I don't apply any gloss, but that because the set/sol does a good enough job its own.

You can move the decals around with the SET, just remember to be gentle, you really want the decal to be about 85% in place when you set it to the model. The set/sol actually melts the decal plastic film. With some practice you will figure it out. Just go slow..and the results will be worth the work.
