How Do You Fit Warped Hood

[69NovaYenko]

Have vintage Jo-Han kit but it has a slightly warped hood. Looking for any suggestions on how to fit it.

The first thing is, that you probably should have addressed it before paint.

It's hard to tell, but it looks like it has a fairly mild twist, but a pretty pronounced bow.

You could try putting it in a tub of hot water, putting enough weight on top to press it flat, and then let it cool like that.

I haven't had a lot of luck fixing warped parts myself.

I usually just try to "massage" them out with a little careful bending if they're mild, but something this pronounced will probably require some sort of heat solution.

First thing is to find the fender location,..before fitting the hood,... then come back and, under hot water, over twist, slowly, the hood and cold water stay the twist,...

This is a builder I`m attempting to rebuild; it was painted when I acquired it.

I assure you I would not have wasted paint nor my time to apply several color coats to it then attempt to straighten the hood on the back end!

Got ya Greg.

I assumed, when I saw that the body was attached to a paint rack in the photo, that it had just been painted.

I agree, maybe a food dehydrator could be of some use for warming up the plastic in this case. With it's possibility to create a continous and controllable temperature window, I gather this will be more effective than hot water, hairdryer etc.

Hmm...now that`s a thought!

Either prop it open or glue it shut. -RRR

Be careful with the food dehydrator it's just as likely to make the warp worse .

Been following this topic and by no means do I have first hand experience but, considering any attempt to soften the plastic may soften the paint as well, I would think that the paint may get damaged while manipulating the plastic to straighten it out. If this was my project I think I would just strip it first then try any or all the great ideas for softening and straightening it then repaint! Just my two cents!?

Yes, the same as you'll ALWAYS have to be, using one for this purpose. It goes without saying that a FH with temperature control and timer should be used. Low temperature setting and frequent control of the plastic's state is mandatory.

I guess the paint is not the issue here, as far as I understand, the paint was already on when he bought it, so he'll likely strip off the paint anyway...
