I tried a new High Build Primer

[NO_H2O]

I tried a new High Build primer from Evercoat called Slick Sand. I don't know how long it has been around but it kicks @$$ and it is priced right. It builds nice and thick and almost no shrinkage. I'm told it will cure out very hard. In fact I was told to have all blocking and sanding done within days of shooting or it will take 4 times as long to do.
Anyone else tried this stuff?
