The death of a Model

[hawkeye649]

The death of my 1990 Jimmy build up. The primer on this truck had been refusing to cure, and I had been using the defrost on my toaster oven to help cure it. For three days I'd been throwing the model in here, and had done it 3 times the day this happened. After washing it to lay down some more primer on the recent body work, I put it in for an hour and this is what I came back too.

The body is in OK shape (the floor of the cab was many pieces, so it's warped). I think I might be able to keep one of the doors, but it will need a dent. I might be able to crinkle the hood, and rot out the body now, and remove some of the floor boards to make it look like it's in the middle of a rust restoration. So much for my 1:1 of my truck, it's already past the body work stage.

And I was pretty much done with the frame :-(

Bleh.

Skylar, you GOT to take yerbutt down to Target an get you a 30.00 food DEHYDRATOR!!!! Put yer model in THAT the next time you need to dry paint! That's wat they're designed for! One of the BEST investments you'll EVER make! An I do understand the Baby Jesus's grief. I BEEN thru it an I speak from expierience!!!!

If it were me I'd just work with what God had given me. To me it looks like a good candidate for a junker.

Well, now you have one heck of an addition to your junk box! Maybe you can scavenge it for parts?

Most important, why did the primer fail to cure? What did you use for a primer? How much did you apply?

I am trying to figure out if the model warped due to heat, or chemical reaction, or both?

Spyder the Interrogator! ;)

You could make it part of a body shop diorama.

Maybe turn it into a beat up rock crawler? Sorry to hear of your misfortune however thanks for posting so others don't make the same mistake.

One might say that that model is toast !!! Excuse the pun. Looks like the frame is good. Built it as a super detailed chassis and display it as that.

What brand/type of primer did you use? This bit of information will help us help you prevent this from happening again.

Even that will be tough - much of the damage looks like warped plastic, not bent metal.... The vent window frames are ridiculously mangled, the doors are just saggy (only way I can describe it) and the floor boards shrunk to a type of "hour glass" shape when viewed from above.

I'm already looking at it with junker prospects, but this has been a WIP for 4 years.

The primer was Testors spray enamel 1237 flat gray primer. The can was room temperature, and sprayed in my cellar (chilly but not freezing 55 I'd guess?). Once it had dried to the touch, I brought it up stairs and put it in the sun to dry. Later that night, it still wasn't dry. Then I started the toaster process (which I have used for years) and it was helping - and had gotten it to the point I was willing to prime it again (with something else). So I did some body work, washed it, and put it in the oven again to dry (the doors had gotten water in them since they are hollow). The primer gray from the before pictures is the same primer, same can, and I had no problems with it. Shaken well too. I was just using it as "high fill" for the final body work. All this body work was done with personal (email) help from Bill Geary - watch pin strikers and everything.

Since I was drying water, I'd put it through two 1/2 hour sessions. It was about time for bed so I put it on for 1 hour (max on the timer) and turned down the heat.

It's exacerbated by the different materials used in the build. Two different models, evergreen, and the gray plastic from a CD jewel case (way back when I was poor/highschool).

I had been thinking of making a diorama where the body was on a lift being lowered onto the frame, like it was in final assembly (hence the cleanliness of the build). Guess now I just need to roll back - guess I read how to make welded patch panels for a reason now.

It was supposed to be a crawler/mudder etc. More a concept truck of what I'd like to turn my 1:1 into. I had plans to bling it up a little more than I would w/ my truck (those skid plates for example)

This thing must have been 'toasted' 10x or more in the 3 days before this happened. I think this was a time issue.

From what it sounds like you used a clean metal primer. I made the same mistake once, i had to eventually scrape the paint off the body.

[hawkeye649]

THE PRIMER TACKED UP AGAIN! AAAAHHHHH!

[Marc @ MPC Motorsports]

Testors enamel primer really isn't primer. You should use Testors Model Master lacquer primer, Tamiya lacquer primer, or Duplicolor Sandable Automotive primer. Testors enamel primer won't dry and is not sandable.

[jbwelda]

tamiya. ditch that MM ###### and use the best. yeah its expensive...but time is expensive too and so is a kit.

repeat: tamiya.

Hmm, it's been years, but I remember it drying. I certainly don't remember it clogging the sand paper or being sticky?? That's horrible though. I ruined a model that had doors that clicked shut with watch pin striker bolts, trying to dry primer that wont dry? Why would anyone make a paint that doesn't dry???

Tamiya is the best and it's all I use. The others work if you can't get Tamiya.
