    Default paint problems

    Ok here is one for the paint guys I am painting a high lift body with testors one coat lacqure the body was primed with testors primer and then wet sanded it.The primer is well cured I used my compressor and blew off any water then let it sit for an hour or so befor shooting the color but when I sprayed the first very thin color coat it is running off like water off a duck. Man is it making a mess, I dont get it I have never had this problem befor any ideas? What would cause this? I am going to have to let it cure real good and sand it all off

    it might sound like a dumb question but was the primer meant for laquer..self etching primer.laquers do some really funny stuff sometimes and by funny i mean NOT funny

    The primer was a testors primer that I sprayed a long time ago at least a couple of months I just went and dug the can out and guess what it is a enamel primer I am thinking this could be the problem plus I wet sanded it to a super smooth surface

    i could be wrong but i think its the primer..i dont think the surface finish is the problem, the smoother you get things from the get go, the less work you have rubbing out the final coat..my dad used to run a custom paint shop for bikes and i used to do alot of the prep work..that was 25 yrs ago i mean you dont want your primer polished glassy smooth but you definatly want to get it smooth and clean..i,m pretty sure laquers bond with the primer chemicaly..i have a good bud who,s an auto painter, i,ll ask him tommorow
