body work question

[Footjoy]

If you can open picture when I sanded with a flatboard the high spots popped up. nLook like maybe weld spots to inner structure. My question is how do I attack this problem

Did you apply a high build primer? If not, I would apply one or more coats followed by a guide coat and then block it. Repeat if needed.

Just my opinion, not an expert by any means.

Looks like you have some low spots as well as high spots. Take a flat head body hamer and LIGHTLY tap the high spots down and if needed apply a light coat of poly filler to have a uniform surface. Than block sand that all smooth and than apply a filling primer surfacer. If you are looking to get it realy stright than I would apply a spray poly surfacer first than blook that and than go to a filler primer. Hope this helps.

I might suggest not trying to flatten the high spots. Those lows are not really that low and with limited experiance you can cause more trouble then good trying to work the high spots. Keep in mind for every action there is a reaction with sheetmetal shaping. You may likely get a worse reaction then the area you fix. If it is not "beer canning" poping in and out real easy, I would not mess with it.

I think I would lay a coat of high quality lightweigh filler or polyester putty in the low spots only, block it down, then skim the entire surface and block the entire surface.

Slick sand primer maybe?

Frank is right I was thinking what I would do with that panel. What he said. You could mess that panel up and make more work for your self.
