Theres a few common mistakes I still see all the time. first is with the masking before the primer I see a lot of guys masking too close to the bodywork and priming right up to the paper creating a hard primer line,the problem is when that line is sanded out it'll still show through as a ghost line.The proper way would be to mask of well beyond where the primer is, 3-5inches or more.
Second and even more common mistake is only sanding to 180 and priming. Sanding to 180 on the filler work is ok and wont be any trouble but the surrounding painted area needs to be takin down to 320 so theres a smooth transistion from 180 to 320 for the primer to stick to,going from 180 to shiny paint just dont cut it. and please never prime unsanded paint,I see this all the time,someone will prime 4-5 " past the sanded part and all it does is waste valuable time sanding it all back off,hours in some cases ...A good rule to go by is when you mask for primer the tape should never be stuck to shiny paint ,only stick the tape on something thats been 320 sanded (320 dry or 400 wet)
So you see, your primer IS important but knowing WHAT kind primer to use and where and proper preping is MOST important. Just using the absolute best primer on the planet wont get you a better job...PREP is everything in this biz....
