Post 12-Bolt Rebuild Question

When I picked up my 69' Camaro I was able to get a used 12-bolt thrown in. It turned out to be very used. It has a lot of surface rust on it but the gears/axel turns smoothly. I have been looking around for a way to get the rusted outer surface in order before I have it rebuilt. I was recommended a product called POR-15. Here is the web link:

<a href="http://www.por15.com" target="_blank">http://www.por15.com</a>

Does anyone have experience with this product. Do you recommend sand blasting and painting instead?

Also, what would be a reasonable cost for rebuilding a 12-bolt? Any help is appreciated.

Joe

Thanks for the advice about sandblasting. I am glad the POR-15 product seems a good one. I was impressed by their literature and a friend says it's a really good product. I would bet it's pretty toxic though. It looks like it will cost me $50 bucks for the products recommended.

This is what the guy at POR-15 advised in an email:

I would recommend removing any paint and loose rust from the housing first. Next, clean and prep the surface with our Marine Clean and Metal Ready. Each product is sprayed on then rinsed with water after 15-20 minutes. Allow the surface to dry thoroughly then apply two
thin covering coats of POR-15 to the surface. I would suggest brushing on the POR-15. It
would be much easier to do than spraying. You will waste quite a bit of paint by spraying. Brushing will not leave any brush marks. This is what we recommend. If you must spray POR-15 make sure to wear a respirator and spray suit. You will need to use a fresh air system if you are spraying indoors. If thinning is necessary you must use our Solvent, no more than 5%. Make sure to apply thin covering coats, if applied too heavy the POR-15 will not adhere to the surface then you will have to start from the beginning. If you are not familiar with spraying on paint then I would suggest brushing on the POR-15.

(1) quart Marine Clean
(1) 20oz. Metal Ready
(1)quart POR-15.
