Hi, i bought a car with a dent in the back. I am now fixing it. I have beaton it back in to its inital state roughly and am going to fill/fibreglass small cracks etc. I am fine up to this point, and need a bit of help getting the right colour match, I have the right colour paint 100% for my car, however i have sprayed up a few bits already with it and still does not seem to match. Could some one please help me with the method of spraying so it matches the rest of the car and dosent stand out like a sore thumb. Thanks.
