i painted my ek championship white about a month ago and after we were finished we noticed that the doors were yellow where we bondo'd but we only used spray primer. Is there a certain sealer that u can use so that the bondo doesnt react with the paint and come through? Someone get back to me asap.

 

so u primed over the bondo? i would recommend sealing the panel that u are painting. if u are intending on painting the whole car, i would recommend sealing the whole car

 

well if you already painted the car,assuming you used catalyst with the paint or the clear, you can just scuff and re-shoot the panels with the spots, but in the future, you need to apply 2k primer or some polyester primer with MEKP hardener, stay away from rattle can garbage!

 

^^^Yep, rattle can primer is ok in some situations but for real work its poop in a can. The filler went right through it and bled into the base. I've wiped that **** off with wax/ degreaser, some of it is that weak. 2k high build, and you can base right over that.

 

Yep,unless he spends $15 a can of U-Pol,SEM or 3M,most that parts store garbage will wipe right off with prep-solv
