there isn't too much paint on the rads... They all need a good cleaning... We where thinking of building rad boxes b/c we have dogs and the one liked to lay on heater vents. I don't really want her to try and lay on a rad... Much hotter than forced air vents... Plus, she has tried to jump on the one behind the couch when she realized there was warmth coming out of it.. LOL.. I tried to clean an vent and to be honest now that rad ticks at the vent... Sooo I'm thinking it's time to get new vents and fast b/c it getting cold in the evenings... and I want to sleep with the heat on with out tick tick, clank!
