I had a scratch on one of the doors of my car so I went to an auto guy who fixed and repainted it .. But my question is the door is a bit shiny compared to the other parts and you will know something was done there ... The guy said with time and washing , it will fade and become uniform .. Please how true is this ?? Am worried

if the fix was accurately done, it would have been hard to notice, but it really depends on the tripple constraint as well. the scope of damage and the repair budget and the skill level of the technician. best before you rush to fix a car, get recommendations from someone who has been in a similar shoe.
