I got most of my truck(86 f250) dissasembled and am getting ready to start the bodywork.I have a question about what to do about stripping the original paint.The top part of the truck<its a two tone-see gallery,has been redone and is starting to delaminate. I know i will have to take that part down thru the new paint layers,or should i take it all down to bare metal or just sand thru the clearcoat on the areas that haven't been repainted?I am planning on painting it one color .
You can go about it in a couple of ways really, it's more of a choice of how labor intensive you want to be with it.
If you're just wanting to give it a good fresh coat of paint, you can use a DA and sand it out, take your time to make sure everything feathers out properly, then give it a good coat of primer, block it and get ready for paint.
The other option is to strip the entire vehicle, whether it be chemically or mechanically is again up to you and of course budget minded. I do both depending on the job and the customer. If I'm just doing a repaint, I'll sand it out good and smooth, then use scotch-brite to get the edges you can't always get with sandpaper ( works great for those tight areas in the doorjambs ). If I'm doing a restoration job, I always strip it back to bare metal, getting rid of any existing bodyfillers and possible rust that hasn't been addressed yet.
Both ways are good ways to go, it just depends on what exactly you have in mind and your expectations of the final result. Both ways will get you a nice clean paint job, but one thing to remember, every paint job is only as good as the prep work that went into it.
Good luck and if you need any other help, feel free to ask.
Chemical stripping is one way to go if your looking for a show truck. It is very
labor intensive. Most guys use marine or aircraft stripper. If it is a work truck
DA what you can and go from there. A good paint job is 95% prep.
Newbie question here. What is DA? I have a 1970 that I am doing a functional restore too. It will be a working truck. My goal is to get rid of the body cancer, pound out the dents that are easy to get to, then prep and paint it.
Thanks,

A DA is a dual action sander, it rotates and vibrates for sanding puposes but with a change on the axle itself will turn into a grinder. Just make sure when you're ready to sand you don't have it on the grinder setting. ( laughs,, everyone makes that mistake at least once ) You can tell by not only the speed of the DA but the vibe mode as well.
Weather here has slowed my progress,got it ripped apart,have to pull bed off of frame yet. i am going to pain the frame while it apart.I will probably sand the paint down to the factory layer than use paint stripper. I use a DA at work,I don't have a compressor that will run a da well at home though.
I wondered about an electric da.seems like there would be one out there.I have to get a grinder also to use w/cut-off wheels to remove old sheetmetal.Wonder if i can put a sanding disc on that and use,just have to keep it moving so I don't dig into the body.
Is a DA sander the same as a Random Orbital Sander?
no.
a DA is dual action, combines random orbital with the rotary type....DA is best in the hands of someone inexperienced and great for polishing/waxing
A DA is best in the hands of experienced professionals. It is not designed or used
for polishing or waxing.
although this one says its for polishing, not sanding, if you look at any DA sander, it says it's for polishing....and the rotaries are MUCH more apt to burn through paint and take you to the metal....guess it pays to read
You're talking about a buffer though rsylvstr, the DA we're referring to is an actual sander, there are wheels available to convert what you listed into a sander / grinder, but try using that all day and your shoulders will be screaming at you. lol

gotcha, i think...thanks for the clarification....thought they were the same...then again, i guess the RPM would differ.
Yes and no,,, they do have buffers with variable speed either on the trigger or like the DeWalt with a thumbwheel. There is however an actual electric DA, I think Milwaukee still makes it.
