Painting EPO or similar foam

[Solitaire]

I started this in another thread, but have a few more questions regarding painting foam products.

I've done some reading and see a miriad of different ways to accomplish the same thing. I'm looking for quick and easy.

Firstly, what's a good product for priming EPO, EPS,EPP etc?
Secondly, do you guys fill the mold marks? And with what material?

EPO and EPP will take just about any paint in my expeience. Haven't tried much on EPS. Priming with Krylon primer really makes a difference.

Light weight spackle works great with EPO and Z foam. It can get a little frustrating though if your trying to make the plane look like its other than a foam plane. Seal the spackle with minwax diluted by 10%-20% alcohol if you want the spackle to "disappear".

Q&E: Wipe down unpainted foam with alcohol, spray a light coat of Krylon primer followed by 2-3 light coats of color.

Ok, thanks, it looks like a trip to the hardware store. I've been leary about attempting the project knowing that some substances will eat the foam.

I don't plan on removing all the evidence of the foam pattern, just need to fill a couple of fairly deep mold indents. It should also help with the aerodynamics.

Just to be sure of compatibility; take an area of foam that is going to be hidden in the finished model and test it by spraying and brushing the paint you want to use in that spot.

One of the issues with spray paints can be the accelerant that's used in the paint. Some of those accelerants eat some foams. Spraying with light coats, a good 12-14" above the foam, usually eliminates the problem.

We're looking forward to some photos of the project.

You don't see it much anymore but it is out there Lacquer paint is a no no for foam for plastic it is great because it would eat into the plastic a little before the thinner flashed off. But on foam it eats right through. Ray
