I did some crude testing to cure enamel painted parts with heat. I don't have a dehydrator but a simple droplight with 100W bulb and a 12" tall cardboard box served the purpose.
I put two styrene scraps in the box, an old door and trunklid. With the light on for an hour, the parts reached 128 degrees and the box a bit less except right near the bulb. I tested frequently using my laser heat detection gun. For a fun fact, the 100W gets to 350 degrees. The outside of the box (about 12 x 12 x 8) gets to the low 90's.
Well the parts didn't deform or melt (good) but I'd like to hear what you folks with dehydrators run them at and for how long.
I can always go to like 60W for 12 hours or so-just want to be safe and cure paint without warping.
Thanks.

A 60 watt bulb used in a childs EZ Bake oven gets up to 350 degrees.

And that's safe for children??
So far only getting the parts to 110 on 60W-after one hour.

Its actually not safe for Children. Thats why they just totally reshaped and organized the EZ Bake oven eliminating the lightbulb totally.

Here's what I've built. It works great. Enamel is dry to the touch in a couple of hours. I usually leave stuff in there over night, just to be safe.

Great info and great idea. Thanks.
And we have something else in common-both Cobra builders!
My little experiment is doing fine at 109 degrees for the parts. But I surely will build a clone to yours and keep it in the basement. Even have the left-over foil insulation!
Thanks for sharing.

Basically, that's what they are, just big models. Yours looks like mine does now. The new owner painted it black. Yours is a beautiful ride too.
