I'm planning on getting some body work done while I'm off work, but I am not ready to finish it all the way through to a full paint job. What can I use to cheaply seal off bare metal areas for a good 6 months - 1 year time frame. I would go with a product like rust bullet, por-15, etc... , but I'm looking to go cheap now and then at a later point in time I'll strip the whole body and use a more expensive rust encapsulator.
