hi does anybody have any tips on how to blend to old paint under the formula door decals to match the rest of the car or will i need new paint in that spot?

 

im not totally sure what your asking. but i'll tell you what i think. remove the decal. have the spot painted. pull the tape off. sand the line were the tape and the paint meet. then take a buffer to in. put a new decal on the door. then it should look great. i hope this is the answer to your question
