Noob sanding question

[DSMSpoolin]

sanding down my friends s13 hood to give it a fresh coat of paint i was wondering if i should take it down to the metal because it has a little surface rust.

[ChūkiS13]

I would definitely take it all the way down and prime/paint. Don't paint over the rust unless you want it to bubble up under the paint and cause more problems in the future.

Hows is the paint on the hood? Its always easier to just scuff and shoot it, surface rust can be easily sanded down with a DA. But make sure to use a sealer or a decent 2k primer.

ospho, rust inhibitor, or take it down past the rust if you dont want to use those, shoot it with a good high build primer and block it down so there wont be any dimples or low spots.

tanks guys. what i did was sanded it down to the metal and sanded off the rust wherever it was present. i also made sure i did it as level as possible as im using a circular sander and not a belt sander or anything like that. i am also keeping the entire car in the garage to stop any more rust from forming. im new to painting. i mostly just build cars then take them to macco =D but my friend wanted this done right. i also have a sand blaster but im too lazy to bust it out and i dont want to get sand all over my garage. lol. ANY input on making this car look great is appreciated. so please feel free to shoot me as many tips as possible and now without further adue. the pictures lol.



this is what i have done so far.







heres the sander i have been using





and thats the paint gun i shall be using.... post away!

and yes i am going to sand down the entire car and repaint it. i just decided to start with the hood >.< also the hatch has 2 quite bad rust spots. they haven't rusted through yet so im hoping i can just sand those down as well. ill post pictures of that too if you guys wanna see so you guys can give me some pointers on how to do that right as well.

yeah you can just get a can of rust inhibitor spray, the one that i am thinking of says that it turns rust into primer on the label, i will get the brand when i go back to my shop tomorrow.

sanding to panels bare metal...

you should only take an area to bare metal if a metal repair is necessary. in the case of surace rust you should only take a scuff on it and hit it with a good sealer primer. if the meta has pitting from the rust, then take the immediate area to bare metal and feather out the paint around it. bare metal is best coated with self etching primer, but make sure to clean the meta with acetone or something similar to remove any oils or contaminents from the metal. wouldn't hurt to lay a coat of sealer primer over it. this is an area where alot of people screw up. not only is it very time consuming and pointless to take a panel to bare metal, it is VERY difficult to get good adhesion without proper prep and equipment, and most people just are't willing to put the time and effort into it. plus factory paint and primer is applied in about the best case scenario so it best left as a bsae to work from if possible

Shit. i already sanded down most of the hood already >.< but for the rest of the car should i just sand the old clear coat off then and primer over the old paint?
