Karel, I've never used that but I have and am using these....
This one is formulated exactly as Pro-weld. Micromarks "SameStuff" says it's like proweld, although it doesn't show the composition for comparison....but it's priced exactly like Pro Weld. I'd stick with Pro-weld or any of the two Plastruct brands.....stay away from Plastructs' Weldene, it's only for styrene and the hold isn't that strong.
