I have a 1977 Corvette that I am considering repainting. I have a
shop that will work with me and help me through the job, as I have
repainted cars etc. over the years with good results. I am going to
do the prep work and they will paint it. The questions I have are:
The car has the original Corvette orange paint that is in pretty good
shape with a few chips, blems, etc and some cracking or crazing on the
driver's quarter panel. Many folks say to sand or strip down to the
fiberglass ( I agree if your are totally restoring and plan on showing
the car). I want the car to look better and have a tougher finish as
the car will be driven. The question is, is it a unwise decision to
paint over the old paint that is sound? Is the cracking in the paint
going to be an issue if it is sanded down beyond the cracking?
What type of paint is best for a repaint, as I am looking at Dupont
base coat clear coat? I am assuming they can come up with a match on
the original paint code, but I have not check into it yet.
I will be priming the car, but what primer is best with the old paint
and the new paint? A special bonder etc.?
I am looking for any tips or suggestions in this area. I want to do
what it right, but I really want to get as many opinions as I can.
Dad is the expert here on painting, but my experience has been that once the
paint cracks on a Corvette, the only way to have a good paint job after is
to remove that old cracked paint.
Fiberglass is flexible, so paint is often cracked even if you can't see it.
Paint also tends to peel off when flexed too much, once the paint gets too
Some say that the two-part epoxy primers will cover and prevent cracks in
the new paint, but at the cost of painting, is it really worth the chance?
Spending an extra day or two to strip is a worthwhile investment IMHO.
I don't like sanding because most sand too far, often scalloping the
surface, so the painted surface is not smooth anymore. Sanding a metal
panel, unless you are very aggressive, usually stops when you are at bare
metal. But on fiberglass, you just keep going because the fiberglass sands
away rather than stopping you. This is how you create those scalloped
Stripper has its own problems, in that it frequently soaks into the
fiberglass panel or sticks in holes and then resurfaces later under the
paint, causing it to bubble. The solution is to strip quickly, wash with
lots of water, soap and water, and thoroughly dry out. Letting it bake in
the hot sun often helps draw anything that soaked into the panel out. So to
strip today, and paint tomorrow, IMHO, is asking for problems. Strip today
in small sections, wash frequently, and let it bake in the sun or heat for
several days or more. Paint a few weeks after stripping.
I'm sure Dad will chime in on this, and let you know if I am all wet, but so
far, I have been lucky doing this.
