sealing eps- which stuff?

[55NSup]

Thanks Byron for the pro level info. Im going ahead with the latex based filler. Its my first sup and if the design and build goes well im sure I will build another. Might be able to sell it for material cost.

If anyone asks me to make one and get paid for real, id use the microballons and epoxy, so its most durable.

My CF and materials arrived from Easy Composites in the UK. Seems like a good supplier. Cheaper than RG in Germany.
