primer help

i have a new can of spray primer (model primer) that does not say that it is sandable. here's the question: i tried spraying this thing at various distances and the result is always a stringy coat. i sand it down anyway which doesn't give an ideal finish but works. am i just not shaking the can long enough? i've shook it for over five minutes and got my girlfriend to shake it for another five thereafter with no success. any thoughts?

ever thought of a bad can of primer? :)

this was the first time i've really taken the time to prime my car bodies so i'm not too sure what to expect. it could be but is there any *special* way to prep the can of primer before use? or can i just shoot right after shaking the can?

Ok I'm no expert but i read alot so this is my input:

Put the can in hot water (not boiling water!) to better prep the primer for 10mins. In fact I do this all the time for my other can sprays.

Get your kit ready when the time is up.

Take and shake the can and spray it.

Another tip which I learn to control the pressure of spray cans is to take out the nozzle and put that little japanese coin(the 1 with the square hole in the middle of the coin type) in and put back the nozzle. With the coin there, it limits your spraying pressure.

Hope I got this right. Check the FAQ for the correct distance.
