Quoted from SDM0:The house heat is lower this winter so it is around 30-40 degrees but some guys keep these in their garages
It's 30-40 degrees INSIDE your house?
You put tape, and triple thick, over screened ink on glass. If it's normally like 70 inside your house, and then it's 30-40, you just created a huge temp variance. All of these things expand and contract at different rates with temperature changes. The more times they're going through that thermal expansion and contraction cycle, the faster you're going to see issues.
Personally, I've decided that triple thick is only a last resort option to try and stop an already flaking glass. I've seen way too many stories like this over the 6 years I've been in the hobby, and it really does seem to me like spraying this stuff is at *best* a 50/50 shot that it does what's intended or not.
