I'm pretty new at this so heres my question, what am I supposed to do about this stuff?

<a href="http://hotrodders.com/photos/00007475/Car_005.jpg" target="_blank">Rust Pic 1</a>

<a href="http://hotrodders.com/photos/00007475/Car_004.jpg" target="_blank">Rust Pic 2</a>

Should I have someone cut the pieces out or should I order new pans or should I just cover the whole mess with por 15? If I do por 15 should I cover every available surface and what do I do about places I can't get to like in the doors and inside the quarter panels?

In pic one cover it with por15 and move on, pic 2 you will need to cut out the metal pictured in the top of the pic and replace it with a patch panel then cover it with por15(both sides, underneith and on top)
You can't completely cover every inch of your cars sheet metal with Por15, its just not posible. Dont worry about the inside of the 1/4's and etc, just cover the stuff you can get to like fenders and floors/trunk and anywhere where water or mud might build up. Threst should be fine.

One of the Pro shops around here would grind out/ clean out the rust, Tape the under side and fill the holes with fiber glass resin then paint and under coat. I am not sure if I would do it but it looks good and they win first at many shows.

hey chapo, the fiberglass thing you described, a buddy of mine bought a 1953 Cadillac conv. this car had the fiberglass trick done to the floors,
it looked very nice indeed for about a year, the problem is that when fiberglass ages the stuff gets hard, so whenever the body flexes (quite normal in a convertible) there will be cracks in the fiberglass in wich moisture and dirt will collect, well i believe you can guess what happens next right. this supposedly ground up, frame off restored $65000 car suffered quite a bit from this showwinning trick, and we had to take out the whole floor and install a complete new one in order to undo the damage, so just my advice stay away from fiberglass. just repair what needs to be done, por15 is pretty good if there is some surface rust, but if there are new patchpanels available why not use them and restore your car like it should have been done, i envy you guys in the states, so many good resources to get quality parts. if i was living there life would have been so much easier. well, anyway, do what you think is best. and enjoy a great hobby.

regards Bas

Before you cover with POR-15 clean the rust off. In pic #1 I would clean it all off before you coat it. POR-15 is not a miracle cure for rust. If the rust is laminated then the POR-15 would only cover the top coat of rust leaving the underneath layers to continue to do their thing. In pic #2, no bigger than what it looks you can cut it out and weld a patch in. One other thing after you clean the rust off. Wait until it's dark, put a trouble light underneath, and check for holes. Pinholes will show up real well in these conditions. If you have quite a few, then the metal is thin and should be replaced. Over the Net it is hard to really determine what shape the metal is actually in and we can only offer different ideas as to what options you have. Ultimately it is your determination as to the actual shape the metal is in. But if the car is a keeper then do it right the first time.

i had some pin holes in my camaros floor from inside moisture so first i wire brushed it all off then dabbed some all-metal over it. it had no undercoating but soon will in spring, i shoulda por'd it too but was in too big a hurry. i replaced all the weatherstripping so now no water gets in so there shouldnt be any more rust. i held my drop light under the floor to see every little hole. maybe next time, WHEN I DONT HAVE TO BE OUTTA THE HOUSE AT THE END OF THE WEEK!! this was just for the first pic. the second one is terminal=new metal peice. :(

thanks for all the help guys. I'm going to print this out and take it to the garage the next time I go.

Is wirebrushing going to be enough to get the rust off or should I go at it with the grinding wheel for my drill? if I'm in there should I just try and grind it all away till I see clean metal?

rust will turn shiney if you brush it enough. kill it with rust-mort after you brush it. i dont know if por 15 kills it or just covers it. but a cup-shaped wire brush on a drill works the best for me.
