How much clear do you use marty?   I need to buy some for strikes will 1lt do the trick or will i need a few?

You should easily do one playfield with 1ltr.  Probably 2 playfields.

I use standard hardner and no flex-aid at this stage.

I also buy 4ltrs of prepsol but I think I may up to a 20lt next time as its very good for cleaning everything...including cuts in my fingers.

I emailed you about another thing too...
