my car is basicaly a rust bucket. its a solid body but rust in all the usual places and some not.

i used a rough sanding disc on the floorboards tonight and then hit it with brake clean then painted it all with rustoleum. it came out really good and i even had some left so i hit up the front subframe and radiator support too.

my question is how durable is this method? i know you should primer the surfaces and let everything cure but i was at the shop and i only had a couple hours.

my car is gunna be sitting outside this winter and i really dont want to "patch" anything i dont have to. there is a hole in the driver side floor an inch in diameter which definitely needs to be cut out so i didnt sand or paint anything near the hole.

my front fenders are basicaly rotting at the bottom lips where the "mudflaps" bolt to. should i just replace with new fenders or is there a way to save these? i have a complete parts car with mint body up untill the quarter panels

 

When the rust gets bad enough buy a roller and start swapping parts. As plentiful as Fox Mustangs are you will come out way cheaper in the long run. You don't want to keep dumping money into a car that you know is a rust bucket. Know when to call it a day and move on.

 

The rustolium or however you spell it is a short term fix, you need a good drill and numerous wire brushes of different shapes and sizes.then rip it down to bare metal, and then buy POR 15 its a product used for rust prevention sold by many resto shops. i used it on my 68 roadrunner. its a two step process, a primmer and paint. the stuff is awesome. i got mine from year one but you could find it cheaper i'm sure.

 

thats not really an option. anyway, its mostly rust.. not rot. rust can be stopped. thats why i made this thread...

 

Rather than rustoleum, try the Eastwood stuff or Por15. Eastwood has a 2 step deal where you use a rust converter, then an encapsulator. I tried the Por15 stuff, but went with Eastwood due to it being available in spray cans. Plus the tests I've seen showed that the Eastwood stuff was better, although there was a lot of people that loved the Por15 stuff.

 

My dad is restoring a 70 Mustang. We stripped the some stuff down to bare metal and painted them with POR 15. It looked real nice, but in no time there was a surface rust coming through the paint, so we had to strip it down and we repainted the stuff with acrylic. Maybe we just got a bad batch but I would not recommend POR 15.

 

WOW, I had the RR for 5 years after i did the por15 and never had any rust come back it look like new underneath when i sold it. But i guees like with anything we all have differnt experiences, thats why we sit here like turds and write on these forums....were after opinions..

 

Some of our customers have used it and they liked it so he got some, but we did not have good results. The thing I don't understand is we stripped it down to bare metal and it rusted but some of our customers painted it over rust without problems and they did not have problems.

 

doesnt por 15 need rust to activate?

 

I believe you're right, but you can apply it to bare metal with the correct preparation.
