in my opinion...pretty much used everything...seriously,and sikkens has never left me stranded..the only thing it ever did was slow me down a tad...i mean that literally...if you try rushing it it will lift in certain areas,(like base coat hitting uncured clear) let it dry properly and it's the best...it costs are twice that of other but you get what you pay for..
the only real draw back is it's the most dangerous to use as it's formulas are high VOC's and msds sheets MUST be followed,as stated:
"used best with fresh air systems"
glasurit second for me.
