Projects Media Blasting or Dipping

Hey guys,

I am not sure where the best place to post my question so I apologize if this is not the best forum.

I am restoring a 55 Chevy and picked up a spare trunk lid and front hood to practice with first.

How do I clean and prep the trunk and hood when they have so much bracing that you cannot reach with a DA sander? See picture below.

If I media blast then I would still think there could be crevices that might still continue to hold rust. If I Dip the trunk and hood, how do I get epoxy into the crevices to properly seal the metal.

I have tried searching for some specialized spray head but don't know enough to find if the right tool exists?

I saw a video on You Tube where a guy bought a cheap sprayer at Harbor Freight and sprayed POR 15. Has anyone here tried this approach to sealing the underside of the trunk and hood?

Sure appreciate the advice

Thanks

 

anyone?

 

Hello, I'm new to the HAMB, but have built one old car, and some keeps in the past. I personally like the ruberized undercoating that is sold at wal marts. It's in the automotive section where paint is. It comes in aerosol cans and is super cheap. I did the whole bottom of my model A with about 8 cans, no cleaning of paint sprayers, and I think it cost less then $40. As far as prepping the metal goes, I had my parts sand blasted before any work started.

DO NOT-I repeat DO NOT sandblast that hood or trunklid !

 

why???......because they will warp and oil can......

 

Either cut it out and sand it. And them put it back together. Or treat it with phosphoric acid and be done with it.

What about soda blasting?

To do a phosphoric acid dip I would ***ume I need to find a company that will do that?

 

Just spray it down with something like phosphoric etch and prep that you get from Home Depot. It won't remove paint. But it will remove some rust. And convert what's left to a paintable surface.

Thanks for the tip. I also see Home Depot has another product called Corroseal. Both products look to be similiar. I might have to give one or the other a try.

 

I used a product called Miracle Paint sold by Bill Hirsch; I thinned it a little and let it penetrate tight places on the body. It is a moisture cure urethane similar to POR 15.
