A while back I was having a problem with Alumilite White castings having pin-holes in the castings. I contacted Mr. Mark Prent who said to fill the pin-holes wait for the casting to completely cure (I wait 72 to 96 hours) and then mix a small amount of the product then degas before mixing (in this case Alumilite White) with the same color (and with gloves on) rub the area with the pin-holes back and forth dipping a gloved finger into the product and rubbing again. The back and forth motion seems to allow the product to fill these fine pin-holes.
Because my castings are car steering wheels I used Alumilite Slow Set to fill the Alumilite White casting having the pin-holes. The Slow set gave much needed time; I degas before and after mixing and then dipping a gloved finger into the mix of slow set and rubbing the area with the pin holes. Then waiting for 72 to 96 hours I sanded with 1000 grit wet dry sand paper using NOVUS #2 polish to help free the sanding powder. This is until I see only the filled pin holes and then I switch to 1200 grit and 3000 grit wet dry sand paper and using Liquid Ebony polish on the final sanding and buffing. This works.
