left the charger as is, after a day in the dehydrator the testors was hard, humbrol not so much. humbrol isnt bad i like their other colors but ive noticed their gloss black kills testors gloss black by leaps and bounds problem is the 6 month drying time(figuratively speaking). i got a dimmer box but i dont use my dremel i use a harbor freight dremel that has no speed control. its purple just a really bad shade thats no where near the cap kind of purple
