So I am doing some batch casting Alumilite Clear Fast right now. I am measuring out both parts by weight per instruction. I am ending up with small amounts left in the part A and Part B bottles. Rather than waste this, my question is, can this remainder be added to another bottle of Part A or Part B or are the batches in each bottle unique.

.....Yes, you can add the remainder to another part "A" and part"B" bottle of like product with no issues

As long as it's the same product it won't hurt a thing, I do it all the time with Plat 25.

Dont you guys not consistently state NOT to ever measure by weight, and only by volume?!

Did YOU bother to read the original question and subsequent answers? ...absolutely nothing to do with weighing anything, now go troll elsewhere.

Genuinely not trolling. That was a sincere question. I know it wasn’t directly answering his question but I figured it was okay to ask a relevant question from the post in the comment thread. May I ask again? It says in the directions to never weigh by weight but I see people talking about doing so and nobody clarifying anything
In the comments about the difference in instruction. Is weight measurement a better idea?

Just curious which product directions you are referring to as I have not used every Alumilite product......as far as weighing vs. volume measurement (liquid medicine cup...like you get w/ Nyquil) its a users preference ....some swear by volume, others by weighing. Using a Gram scale to weigh is more accurate, especially for smaller pours....as an example: RTV rubber is little more forgiving if your off a few Grams where as with resin you have to be right on the money...a few Grams off with the resin will more than likely end up being disastrous.
MEASURING BY VOLUME: With some big pours, you have little more tolerance where percentages are concerned. Off 3% with a big pour.....lets say 10 lb.s of RTV rubber w/a 3 lb.s of resin pour , you will probably get by with out too much issue. Same 3% with a 40g small resin pour will more than likely result in unwanted results.
I started out pouring rubber-n-resin using the small plastic measuring cups......made the switch to a digital Gram scale and things improved greatly. I've never poured anything myself over 70-80g (resin) but have been witness to some very large rubber molds and resin pours....same concept (weighing) only with a digital bathroom scale.

Thank you!
I was referring to the amazing clear cast. I thought that’s what the OP was using.
I’m gonna do some more research because the paper instructions, the instructional video and website make it so clear not to go by weight, yet so many people seem to. But I am struggling slightly lately so might just throw on another coat using this method and see if it helps!
Thanks again - and for answering me so thoroughly!

I have inquired about this same issue when I wrote to Alumilite saying poor vision made it hard to read the bottom of the meniscus when measuring by volume. Anyhow the proper ratio by weight for ACC, I was told, is part A 100 to part B 85. This should work for any amount. I haven’t found any problems with this approach.

Thanks for sharing that info. I was not aware of the ratio by weight as I use a scale, but good info.to have none the less.
