I would recomend against using it because of several reasons. First, you don't know what kind of reaction it will have with the paint that you used. Second, you don't if it will yellow over a short period of time. They say that you need to keep it out of direct sunlight to keep it from yellowing, but I have found that, that is not always the case. I used a simular product once and it yellowed 2 days after I applied it. I would just recomend spending $3.00 for the Testors to keep from ruining a $30.00 model.
