    no matter what I did the epoxy bubbled so much to the point that it became a FOAM. A waste of my time and money

    Alumilite Clear Slow is my favorite resin. I won't use anything else on deep pours. I've had a few 4,000 gram pours with crystal clear results. Great Job Alumilite!

    I use Alumilite Clear Slow to cast cylinders that I put on my lathe to turn down to make my prototype fishing lures. Easy to work with and turns like a dream in the lathe. I cast those prototypes in some High Strength 3 to make the lures to test and use on the Big Island of Hawaii. Great stuff. It does everything I need. Super satisfied. Thank you Alumilite.

    Clear Slow Brushed On

    Posted by Mark on Apr 29th 2020

    So I was looking for a clearcoat product to brush on to a set of veneered speakers I am building. After some consultation with a company I went with the Alumalite clear slow. Well I am quite pleased with working with the product, in my case it’s soaked into the veneer too much and wind up requiring just as many coats as any other product would.The only reason why I did not give it five stars was because it did not work for the application I needed it for. Other than that I liked the product.
