preping a roof for a vinyal top..please help.

Hey guys, does anyone know a good way to prepare the roof of my roadrunner for a new vinal top? It currently has surface rust and glue(old top) on it. Id imagine it needs sandblasted or scraped, and I was thinking a rust killer or some kind of paint or primer?? Please any good proven ideas welcome. (I dont have alot of cash so I need something thatll work but not something for a show car.)

Remove all old glue and rust to bare metal. repair any rust holes. Wipe down with a good wax and grease remover. Apply a few good coats of Southern Polyurethane self etching epoxy primer following application instructions. Apply an even coat of DAP Landau Top Adhesive to both the top and vinyl. Allow sufficient time for the contact adhesive to dry and apply the vinyl to the top.

SPI epoxy is without a doubt the best epoxy primer on the market at the most competitive price.

Listen to Vince, he's right on IMO. Sometimes I shoot a couple coats of urethane singlestage over the epoxy but it really isn't needed as the epoxy will provide all the corrosion resistance you'll need.

When I was installing Vinyl tops many years ago once the top was prepped I would drape the top over the roof making sure it was centered, then I would fold it back to expose either the right or left side of the car's roof. With the top folded back I could apply glue to one side of the roof and one side of the top and then once the glue was set carefully work the top back down over the glue. With one side glued down I'd then fold it back the other way and apply the glue to the other half. If you apply glue to all of the roof and all of the top you will have a monster that is impossible to deal with, once the two glued surfaces meet there is no repositioning so work carefully so you don't trap any wrinkles.

If your roof is just a little rusty I think you would be better off just sanding it all off and coating it with SPI epoxy.
