I'll answer from my own, non-Honda experience. For rust and holes, there is something on the market called Bondo. Its a resinous kind of product, comes with fiberglass sheets. You places a sheet across the hole, and with a spatula apply the Bondo. When hardened, you sand it smooth, prime and paint. The more patient you are, the better it will look. Let me say that again: the more patient you are, the better it will look. For dull paint, there is a product called Nu-Car. Apply and wipe off just like regular car polish. READ THE LABEL FIRST. Changing you own tires is a b*tch, and I wouldnt try it. Harbor Freight Tools sells a manual changer which I THINK YOU MUST FIRMLY SET INTO A STURDY FLOOR, and then use pry bars to pull the old tire off and put the new one on. Today, only truck tires are changed manually, and truck tires are a little easier than car tires, beleive it or not. Nextly ... I've dealt in scrap and scrap cars, I think you're scrap price might be a little optimistic. Scrap on a true junker RARELY goes over $!50.00. BUT ... you are NOT scrap, because your engine cranks and starts. Thats a Big Deal when you get down to scrap-level automobiles, because if the engine cranks over, the buyer knows at least that the engine is not FROZE, and thats worth a few bucks. And if it starts, thats even better. Aftermarket changes never seem to return their value. And in nine years of that activity, I NEVER had anyone come looking for K&N intakes or fancy headers. Good luck with this, you might fix it, you might be able to unload it. Time will tell. Just dont blow the engine.

For your budget, cut the rust out (as in all of it, if you leave any, it will come back right away), fiberglass and bondo. It is a skill that takes time to learn. Buff whatever paint is left and buy some quality two part paint and clear coat (about 4x the price of a regular rattlecan) for the touchup. Use a good primer as well.

Going to need to go through the engine, start with a compression test. After that there are plenty of options.

sounds like you have a " scrap- car"..........Yes you can damage the wheel,.....OR get hurt if you change the tires yourself, by hand ( no tire machine ),,,,,,,,,,,,,,,,I ' ve done it, but it can be a tough job

no idea

So i recently bought a 95 honda civic Cx , both front tires had no tread at all , and one was flat (had a hole in it , slow leak) 260k miles on the stock D20 V-Tec header with a K&N Suburu intake , and came with 2 new front tires (not put on) Since this car was only 250$ and scap is about that and the tires are almost 200 alone. So the car has a bit a panel rust , probably 3/4 panels , how could I fix that? another thing is , I have it on blocks atm for one tire blew out. I turn the car on every day just so it doesn't sit without being warmed too much , but I started it the other day and it turned over and then it slowly died. I started it again and can keep it going if i rev it a little after start ( what could it be? ) another thing is , the paint is really dull and beat , would a normal spray paint ( cans ) work? I know how to use a spray can , but idk if the paint would wear or not be as nice? I want to fix this car the cheapest I can at the moment for I have no job. Also if anyone out there happens to be a honda head or know anything about honda's if you could give me some information on how much the V-Tec head is worth , was told around 500$ also if I were to blow the engine , would the V-Tec head be ruined in that case? and if the engine just takes a **** will the head still be good to take off and use with another car? so my main questions are , what are the cheapest way to paint , fix rust , my two front tires need changing, is it possible to damage the rim myself?
