2K Hi Build Question

[SSuperDave]

I'm getting ready to buy some, has anyone used the U Pol 4:1? I've used U Pol clear before and it laid out very well. I can't spend PPG money, K38 w/hardner is over $500/gal, but am aware that some of the cheaper brands are good.
Thanks.

I use the upol on everything but top level projects. It's high in talc, and that's supposed to mean excessive shrinkage but I leave my stuff cure for at least a week before sanding anyways. I use spi for upper level projects. K38 is just crazy.

Thanks. I'll be working panel by panel, so shrink time will not matter. I'll look into the SPI as well.

I use Utech 2K100 for high build/blocking. It's 4:1 mix and just under $200 for the gallon and a quart of activator. Been using it for 15+ years.

Thanks Tom, sounds like a reasonable alternative price wise.
