Hey all,
After seeing Larry's video, I've decided to try the mineral spirits trick on my rtv mold.
I make my rtv mold in a solo cup. This prevent clamping and allows an even distribution of pressure around the conical mold.
I have a couple questions before I do this though.
Will the mold return back to the exact original size? About how long does this take? Is there any warping on the original mold when it shrinks back?
The reason why I ask these is that I have to make 2 molds instead of 1 if the original doesn't return back to the exact size it was previously (since I won't be able to use the solo cup as a "clamp" anymore.
Appreciate any info! Thanks!
