Definitely gonna need a better quality paint...I have some blistering/cracking on the firebox lid but, to be honest, that is my fault...I closed the lid before I should have...Still had some pretty tall flames...Lid got too hot. No biggie...Easy fix. No signs of blistering or cracking on the bottom, front side, back side or cleanout door just yet...At least not that I can tell with my flashlight. Fire basket I threw together is 12x12x6 so it keeps the fire 3-4 inches off the sides so that helps...Also the ash pan is about 2.5mm thick and there is about 2.5" clearance from the pan to the fire grate so bottom is fairly protected.
