hey guys i have never used this Hi-Temp Lab metal $hit before and it is cracking after i take it out of my oven to sand it... WHY
This is how i did it:
1) Sand blast piece blow off dust and wipe with solvent.
2) Fill with Lab metal and let air dry for 24 hours.
3) Put it in the oven for 1 hour at a little under 200 degrees celcius.
4) Removed from oven and Sanded lab metal and refill with lab metal. And let air dry for 24 hours.
5) Put it in the oven for 1 hour at a little under 200 degrees celcius.
6) Removed to sand it and it has CRACKED
Too expensive $hit for this too happen.
