High fill primer will fill the little ones but you’re just as likely to end up with little dimples all over so then have to sand all that new primer off to get the surface level. Just as easy to sand it back before starting and not waste all that primer.
That’s what I usually do but this thing has rock chips all over it and didn’t want to sand all the way down in a hundred different spots all over the body and risk having waves in it.
What I do probably isnt the “ideal” way to deal with chips, especially when it comes to corrosion protection. I usually just fill the bigger ones with glaze, sand the glaze flat, then put a couple of coats of a 2K primer over the whole panel. You will end up with dimples from the smaller ones, but once you sand the primer the whole panel will be nice and flat. The only time I really deal with real chipped up panels is with used parts. I have found this to be the fastest way to handle it. I don’t wanna deal with feathering each one out then blocking the whole panel. They just don’t give enough extra time on the used parts to make the whole process worth while.
If it takes too long to feather out each chip and block it and your worried about being wavy strip it 😉
I second the motion from Jayson :clappy :cheers

If it’s bad I just strip it as sanding can be slow, boring, messy and time consuming especially on some modern factory paints they just eat discs!
I usually be mindfull of edges and not getting it anywhere I don’t want it apply product then throw a plastic sheet over it to keep it wet and a lot of old paint sticks to sheet when you lift it of helping keep mess a little contained.On subject of paint stripper what do you guys use? I’m finding it harder to get a proper good quality product new laws are making it weaker and weaker.
DA front end of hood straight across with 80, 180, 400. Shoot 2k primer and sand. Any rock chips that show up just use kombi putty and let air dry for 15 minutes. Then sand the kombi putty with 600 wet. Inspect primer area and whole hood for rock chips that were missed. Then if you want you can either shoot another coat of primer , sand and then shoot base then clear. If you hood has been previously painted then the paint might be pretty thick. If this is the case then make sure to pay attention to feather edges cause they might show up as minute craters after you shoot clear…
Kombi putty/lacquer spot putty is a bad idea,as soon as solvent from paint or primer hits the area it will sink and show a low spot.Mechanical or chemical strip is faster in the long run and the customer ends up with a quality repair.
I agree with what Jayson has been stating. If your going for a high end refinish you probably want to strip the panel, if it’s stone chipping excessively the odds are the underlying paint probably isn’t holding up properly. For freebees and old clunkers I wouldn’t hesitate to toss a bit of 2k putty into it and do a light spot prime. One isolated chip I would usually feather, prime, block.
Strip or feather, Prime and block for best results
