Small Areas of Primer Lifting
I'm in the process of trying to prep some body panels on the Triumph TR6 I'm restoring and have run into an aggravating problem. I had to apply filler to all the fenders and doors.
On a TR6, there is a body line that runs from the front to the rear on both sides of the car about 7 or 8 inches down from the tops of the fenders and doors. I had to apply to various areas above this line and down to this line. Essentially, the filler butts into the horizontal body line at a about 90 degree angle.
In any case, I'm getting minor amounts of primer lifting in a thin line where the filler butts this body line. As I sand the areas out that lift and reattempt, it just happens all over again. Too, where I sand through the primer to either side of these areas along the horizontal body line surface, it starts lifting at those spots, as well, when I try to re-prime.
I'm using Omni 2K primer and am not having any other problems. I just can't seem to get several of these areas to cooperate and have re-attempted 3 or 4 times now.
Is there anything I can spray on these areas to seal them so the primer will stick?
Thanks for any advice you might have.
Scott, was the old paint stripped down to bare metal in the spots that are lifting is there old paint in the lifting areas ?
Scott, can you post a good closeup picture?
Yes, pictures would help, but I would bet its lifting where there is NO filler, but underlying paint...not that putting filler on paint is a good idea. But I bet the problem is where the filler stops and the old paint/bare metal begin
All old paint was stripped away. I guess I can go ahead and totally strip away all the primer on the body line and grind out the filler where it butts up and redo. I'd like to avoid doing that tho'.
I'll try to take a picture on Saturday to show what I'm talking about.
Thanks for the replies thus far.
