At the very least cut back the rusted area to unrusted metal. After that weld-in, screw-in, rivet-in and/or otherwise fill the hole left after neatly removing the rusted area.I have a rust problem a lot of the rust is just surface but there is rust that goes right through the car for example in the trunk so what should I do? Should I sandblast all the rust or should I just fiberglass the rust holes?

Writing from small cell sorry for the errorsI sand blasted my 55. Looked nice.
I had sand everywhere!! In all gauges every crevice in the entire car. I just completely rebuilt my 292 as some joe it got in motor even though it was tapped well. All bearings had to be replaced. Vacuuming power washing did not get all sand ( actually was glass media)
I will never blast a car again
My two cents
Hey thank you for answering alright i have started sanding but what did you use to cut it out did you use a grinder?At the very least cut back the rusted area to unrusted metal. After that weld-in, screw-in, rivet-in and/or otherwise fill the hole left after neatly removing the rusted area.

You use what you have;. a jigsaw or sawzall, a grinder with a cutoff wheel, a hacksaw, a nibbbler, Plasma cutter or torch, or what have you. I do not recommend using a hammer and chisel. It will work but it is brutal and not pretty as well as beating up the edges of the remaining metal. Use what you are comfortable with that will achieve a good base to continue the repair with. If you have doubts of your skill, practice on some scrap metal first.Hey thank you for answering alright i have started sanding but what did you use to cut it out did you use a grinder?

As is typically done, rust is cut out in a uniform shape (square, rectangle etc) and a patch panel welded in. If you plan on keeping the car and improving on it, that would be the preferred way.
I agree. I also had mine “wet” blasted while on a rotisserie. Frame in place but engine and running gear, interior, dash, hood doors and trunk removed. He actually DRY blasted all but the exterior and then washed it down with a rust inhibitor. I followed up with an epoxy primer after blowing all the sand (actually crushed glass) out of the nooks and crannies. I undercoated mine - some do some don’t - personal preference. The blasting will help reveal the rusty places and any previous repairs or bondo. But not everyone chooses to go this far or has the time or resources. There are small portable spot blasters available and this might be sufficient in your situation.I completely stripped my 55 down to a body and a frame. all pieces and parts were dustless blasted. Best thing that I ever did for the car. afterwards I sprayed the car down with Ospho to keep the rust off the metal. This way I can work on the car as long as I want to before priming. The trunk trailing edge ended up having pinhole rust underneath the bottom edge. Instead of cutting this out I put duct tape over the holes and then mixed enough marine epoxy to pour into that space from inside the trunk lid. After it set up I removed the duct tape and sanded the outside area. Then some minor body puty and sanding restored the area. The epoxy effectively sealed the rusted area as the Ospho had killed the rust. By not cutting out the area I eliminated the warpage from cutting and welding and retained the original body lines and decreased my down time. This also strengthened the affected area and cannot be detected with a magnet. I may have misspelled Ospho. It is an acid that changes iron oxide (rust) into Iron Manganese and primer sticks to it with no problem. I have no problem with painting when using this product. I use it on all steel parts.
I did have a problem getting the sanding media off the car as it did stick everywhere but when the car is disasembled a pressure washer works wonders. after pressure washing you let the car dry and spray it down with Ospho. just my 2 cents worth.
