Strange Thing That Happened With Gloss Cote

Posted by MontanaCowboy on Thursday, July 7, 2005 12:52 AM

I applied about 3 coats of Model Master Enamel Gunship Gray on a tail section of an F-15. Then I applied a coat of Testors gloss cote spray paint and put the piece in a closed container. I came back 45 minutes later to find that there was something wrong. There were little pieces of something like large pieces of dust that were underneath the gloss. Before I gloss coted, I made sure there was no dust or anything on the piece. I want to know why this happened and how to fix it. I don't use any primer, is this the cause. Also this was my first airbrushed model.

Could be the model was not cleaned enought. I suggest using primer for anything your going to paint with airbrush and or spray cans. Any chance of you posting a pic of what happended? Dont feel bad either, we all have mistakes.

Testors Gloss Coat is, or at least used to be (I haven't used it in a long time so I'm not real sure), a laquer. If you are going to spray a laquer over an enamel or acrylic the underlying paint has to be THOROUGHLY cured or the laquer can affect the paint underneath. If you are certain the model was clean it's possible that this is what happened.

Music-clear coats (both kinds)-are lacquers (you can tell by the smell) and do cause erosion problems. As you said let the base coat dry and use thin coats of lacquer.

Not all clear coats are laquers, Dan. Testors Model Master clear flat is an acrylic as is PollyScale clear flat. I used the original Testors Gloss Coat many years ago and had a lot of problems with it so I never used it again. I know it was laquer then, but I wasn't sure whether it still is or not.

The local art store where I live has acrylic gloss coats and matt coats on the isle with oils and acrylics for those who paint on canvas, all the ones I have used have worked quite well.

Chasing the ultimate build.

I let the paint cure for like a week before doing it. I'm pretty sure that it was clean when I gloss coted it. I did, afterward, smooth it out with 0000 steel wool. The little pieces then dissappeared. I re-painted it and now it looks like i have too many coats on it! Disapprove [V]

A week should have been sufficient. Sometimes humidity will cause paint to cure slow but a week should certainly be enough.

If you don't like what you have you can always strip the paint and start over. That's a hard decision to make sometimes, but we all wind up doing it sooner or later. You just have to decide whether it's something you are willing to accept or not.

right now my digital isn't working, but it looks like little pieces of string 5mm long and curved all over the piece.

I think I figured it out! Approve [^]

I was spraying a little too far away! I tried it again on another piece, only closer and it turned out darn near perfaect! Am I right, or wrong? Question [?]

Ah, the paint was probably splattering onto the surface since you were too far away? I've had that happen before. Being too far away can be just as detrimental as being too close.
