i have never been really good or fast at body repair. but iv done a bunch of
it over the years.
so in the fall of 2004 i took a body class at the local community college.
learned a lot of good stuff and i feel IM getting fairly good at it. so IM
kinda
foxed at this problem.
i have been working the rear of the car "B" pillar and back. took all the old
paint off and back to bare metal. laid down thin layers of bondo (3M brand)
as needed. flat it our with sanding block. used guide coat to show the low
spots. added bondo to the low spots. repeat many times until guide coat comes
off
all even. ever notice how the second application of bondo has a slightly
different color from the first so that you can still see its outline but cant
feel
it. and the guide coat says there is no low spot?
so i put 2 coats of PPG primer on it. (DP40LF) all those 2nd applications to
fill the low spots showed through like you just had drawn a line round em. i
thought they were really feathered and perfect. i was so bummed out.
so after 4 weeks i guide coat the primer and block it with a 8" long block
sander. add a little more bondo (evercoat metal glaze) in a few spots. guide
coat. block. oh so light bondo. feather it out. guide coat. block sand. this
time
i know it is feathered out sooo nice. in some places the feathered bondo was
so thin it was almost transparent. 2 coats of primer (NCP280)
again...........same results!!!!!!!
its as if the primer is almost too thin or too clear. always i put 2 coats of
primer on.
any ideas on what IM doing wrong? or is it always like this?
is this not a problem? i have not never worked with this HVLP paint before.
will the color coat hide it all? because it looks and feels great, other than
looking like a topographical map.
thanks
