Default Re: Paint a translucent plastic tank?

I dont know if the plastics are similar, but we paint the plastic canopies that come in the R/C heli kits. They are commonly referred to as bleach bottle canopies because that what the material looks like. You can sand it, prime it with what ever you like and it probably wont stay on. The trick to making paint stay is to "flash" the plastic with a propane torch. As you move the torch over the plastic you can see solvents wave off of it. Once that is done it will hold paint well even through a crash. This process works on corroplast too. I have heard it some how crosslinks the surface, but dont really know. All the said you might not want to do a gas tank that has been used, might get a real flash!
