So have you used that product? There is very little info on their site so if you have can I ask a couple questions?

Does it stink when you use it? (Solent based or Indoors ok?)
Does it cure completely clear, or cloudy? At what temp?
Have you used it over water based stain or urethane paint before?

I like the idea of saving money (almost 50% vs system three) but the plastic world stuff has almost zero info. No msds or material sheet. I might end up going system three just because the product is so well reviewed and documented.

The guy at wood essence was zero help. He basically said I would just have to try it out and experiment. I guess its fair to not recommend a product for an improvised use.
