uh oh... i think i need help!!! a well meaning person said they could fix the rusted out spots on my car and i think he used putty, not filler. it's a red color and it took 3 coats with days of drying in between. now it's dry, but cracking and flaking and it looks like rust (?) is coming back through it. i think i could have done it better myself just by watching youtube videos

i know he removed all the rust and sanded, but i think he then just applied the red stuff. any advice is so appreciated, thank you in advance ~
