Painting/curing question.

[AndyLane]

I cured a small batch of jigs in my toaster oven for fifteen minutes at 350. Jigs were hung on rack. The paint on a few of them sagged down from the head pretty bad. They look like miner heads now. What caused this? Too much paint? Too much heat? Hanging upside down? Combination of all?

Typically too much paint initially by getting the head too hot on the initial dip in the powder paint.

I have only painted lead jigs. The bigger and heavyer the jig I had more problems with the drips. I paint jigs up to 3 onces or more.
Powder Pait: Most of us that cure our jig paint have had this happen. The different colors require less heat for a longer time (IMHO). The colors that ran (driped) I would make a list of them and try curing them below 275 degrees for about 25 minutes (not in stone). You will have to learn what works for each color. Pro Tech has a chart that shows the curing temperature for each paint color. Some paint is cured at a higher than 350 deg, but for a shorter time. I have thermometers mounted in each of my toaster ovans so I have a better idea what the temperature is in the ovan. I mounted the thermometers in the back on the sliding plate in the bottom of the toasters, they stay where I wanted them. I have and use over 25 colors of paint and do not have many problems any more.

I hope this helps and enjoy painting your jigs.

I do not use my ovans for food thay are for paint only.

Andy as Jig guy said get an in oven thermometer. They carry them at Walmart, target ... Some of the guys at TU found their ovens off by almost 50 degrees.

That's one - you could have too much paint or yeah the head could be too hot, too cool. We've all been through the learning curve and I still end up with a few every now and then - especially with Columbia Coatings Dormant paints as it's a two part.

If your heat is too high you may see a little puff of smoke, at least that's what happens using the heat gun.

After getting a thermometer I found my oven about 50 degrees too hot when set at 350 (actual temp was 403). I now cure most everything for 15 min at a temp set at about 290-295. I still get an occasional "parrot nose" usually from too much powder. They still fish fine.

Too much paint is the answer...... can happen in two different ways though.

1: Too hot when you dip - it sticks a ton of paint instantly and it all glazes over right away. I like it when it stays just a hair rough. Takes practice to learn how long over your heat source to get each size head hot enough to stick the right amount of paint. That darned learning curve. I would go with LESS time..... doesn't take much heat at all to get it to stick - even after just a second or two it will stick then you can glaze it back over with more heat.

2: Trying to put too many layers of paint will do the same. Start with a pearl base, then add silver to half of it, then add black to the top, then add glitter/clear to the top as well...... equals too much paint and it will drip.
