He is doing some work on my ghia

Don't forget cars rust from the inside out, so bubbling means holes behind in areas you can't see. Just be prepared for the sections of metal replaced to look a lot bigger than the bubbles. I do this every day, and one bubble on the bottom of a door has often been a case of replacing the bottom two inches of the outer door skin to remove the rusted metal that is 90% of the way through, just waiting to become a bubble and a hole.

agreed with helbus, much more so if the rust is around the door sills of the Ghia. one little rust bubble can turn into replacing the complete sill panel

Might as well just sell it and get a new ghia m8

Don't sell it. Just be aware that rust on any old car is going to be bigger than you can see from the outside, and the hours of labour will cost money. Usually between $80 and $110 per hour for a proper restorer.

There are other options, and that is to get a fixed price, however there are situations where that encourages panel beaters to cut corners, as the quicker the job is done, the more money made. For example if someone quoted $9000 for a paint job and did it in 40 hours with cheap $1000 paint and materials, then they have made $200 per hour.

If someone has to stick to the requirements of the job and charges $80 per hour, there is no advantage to cut corners, especially if their shop is full of work.

I would have the shell dipped or blasted to reveal all the RUST

We use a guy who does combination soda and garnet blasting. He uses only soda on any exterior sheetmetal. Garnet is used on all framework and floors.

Soda only removes paint, not rust. It does not warp panels. You must remove the soda once it is done, and De-oxidine, phosphoric acid treat the metal surface.

Garnet removes everything including rust. It will blow holes through anything that is 3/4 rusted through from the back. It will not remove all body deadener and seam sealer. It will warp outer panels.

You must 2 Pak epoxy coat the finished shell within 4 hours, or flash rusting will start at a molecular level. Probably quicker in high humidity. You can mask off the rust repair areas and not epoxy them until you have completed the replacement of panel steel in those areas.

Complete paint strip of the entire body shell to Epoxy coating usually costs between $3000 and $4000 depending on the size of the vehicle.

the only way to attempt a Ghia so many hidden panels and seams

Redi Strip is the best start

wondering? is there a way to spray the insides of the cavities with epoxy?

I had in minds those bulk cavity wax spray guns with lance. but filling it with epoxy 2 pack instead.

What other others ideas and experiences with painting cavities?

wish there was e coat facilities in oz like there is in the US. redi coat would be awesome if they complimented they service with e coat as they are more than halfway there with what they can do already. Would solve a lot of problems. But suppose cost and demand don't call for it yet.

We use to spray inside tubes with an extended head or tube on the spray gun it also went out in a 360 degree pattern

BUT you would have to dip and strip the shell first probably drill some larger holes into the cavities to allow the chemical strip to get right in side

Only way to prepare a Ghia to be repaired

I had mine stripped , best way forward.
