What high build primers do you like to use? Is it better to use one spray on via a paint gun vs a rattle can?
 

You want paint supplies with a catalyst mixed into them so they dry and are set up well.

Rattle can? Nope,
 
Are the air flow needs (your compressor) the same for primer as it is for paint?
 
I restored and prime and painted my two Darts with a cheap kit like this. My good guns are packed away and inaccessible right now. 1.8 tip for primer.

what is it you are priming...the whole car, a door or hood?
The whole car. I have it torn apart now so was going to work on like the roof/qts now than later do the doors, fenders, hoods, truck lid as I have time.
 
..a spray gun is the normal way and hi build primer may spray easier with a bigger 1.6 or 1.7 tip.
In winter i have primed single panels or sections with a high density roller. As long as you will be blocking
your panels the fine texture is no problem.Very easy with no masking, overspray or excessive fumes.
Eastwood have a convenient roll on system just for primers.
 
Whatever you buy look at the mfgs TDS technical data sheet for info like prep and gun tip size.
 
Well, the OP asked what kind of high build primer we like. I like Evercoat Featherfill G2. I always use a 2.2 tip. You can use a 1.8 tip, but I would recommend reducing the mixed primer wit 5-10% Acetone (allowed by Evercoat). This is the best high build primer I have ever used. It sprays on nicely, it covers very nicely, it does not shrink and it sands easily. I always strip to bare metal, do major body work, clean and prep the metal and then spray on a few coats of epoxy primer. Then I do the minor body work with Evercoat Rage Gold Body filler on top of the epoxy. Then I spray 3 coats of G2. Then I block sand with Dura Block sanding blocks and 220, 320, and 400 dry. Then I wet sand with 320, 400 and 600. Then I spray sealer and paint. This primer covers even minor dents and ripples. YOU GET WHAT YOU PAY FOR. Don't go cheap on primer. it is the base for your paint job.

Use a spray gun, not rattle cans. If you're going to strip the car down to bare metal, use epoxy primer first and then use high build over that. Auto paint supplies are expensive nowadays, so be prepared for a little sticker shock when you purchase. Evercoat and UPOL mentioned above are good products. I tend to use Southern Polyurethane primers and clears. I'm not a pro painter like @harrisonm , but just a hobbyist that enjoys doing my own work. I've used all 3 of the brands I just mentioned with good results, but have just gotten in the groove of ordering my primers and clear from SPI. Look on You Tube, for Paint Society channel. I've learned a lot of good tips and practices from Brian. Enjoy your project!

 
i agree wit all above posts. I use CRE exclusively start to finish. If your body is rough sprayable polyester filler
is an easy way to "skim coat" I made my blocks out of cherry hardwood to straighten wavy panels.
 
I just finished my Dart using Limco epoxy and primer. The primer is not considered a high build. I think it turned out nice. Next time I would probably give the Evercoat polyester stuff a try.

I use UPOL with a 1.7 tip.. or 1.5 if i thin it (which i do to lay down a bit smoother on the last coat) and have been very happy with it.. ****'s not cheap though

I agree that UPOL stuff is really good. I would be happy to try their primer, but I like the G2 so much, I am hesitant to try anything else. I did a lot of work to a badly damaged plastic front bumper facia on a car I was flipping once, and I needed to do a lot of filler work on it. U wound up using a UPOL flexible filler designed exactly for what I needed. It worked very well, sanded nicely and the resulting repairs looked great And tou are right; name brand products are not cheap, but you get what you pay for.

Thanks for the glowing compliment, but I am not a pro painter. I am a just a serious hobbyist like you. I've been doing it for about 50 years, so I've gotten pretty good at it. I bet your paint work is just as good as mine. The secret, as you know, is being careful and NOT rushing all bodywork and prep. Then taking your time block sanding primer, and then not rushing the final paint job. I'd like to see some of your paint work.
 
Get all your panel fits to your satisfaction after you think you are done the metal work. After priming block sand everything at least twice using a guide coat....180 then 320. I used Dura Block sanding blocks but there are others. I did a lot of reading and watching Youtube (find the good channels) to learn how to do it properly.
 
LIKE HE SAID!!!!! tip size varies by that companies product!!!!!!
SlickSand Featherfill requires a large tip. I use a large tip like they say to use. Not only does it get tge materials on , it goes on smoothly.
If you look ar guys like the Clown Bad Chad. He uses a gun with to small a tip, high pressure and thinned out. Gets a rough surface He then has to use lots of materials and half is wasted. He could spray half as much or less and get a better job. I also use the old style 3-M disposable cup liner system. Saves clean up. Now that patients ran out even Harbor Freight , Amazon and eBay has refills.
This is a good 2.5 tip

Still spray single stage, base and clear with my old Sharpe HVLP
 
My first complete car paint job and i built a small paint booth in 1/2 the shop with a tarp curtain.
exhausting fumes with large fan can be difficult in cold weather so i only panel paint or prime sections at a time.
clean paint gun and reservoir cup each time...it works ok.
