yes, cold can affect paint

:lol: Underworldaquatics said don't use latex unless your making peel and sticks. I just scraped the paint of back of tank, came of real easy, and that is exactly what it looked like. I shoulda made some blue Dori shapes for my kids. :biggrin:

scrape the laytex off and go buy a 1l can of marine enamal. it takes about two cotes to cover nice and won't come off. use amonia (windex) to clean the tank it won't hurt the fish (unless you dump it in the tank) and it cleans way way better than viniger.

the marine enamal is formulated to be totaly water resistant which is more than can be said about other paints out there.
