What's the weight penalty for not stripping an old 172, just painting over
the old paint, after sanding it first, of course. I'm new at this but
willing to make a go of it. I'd like to use a high-gloss polyurethane and
some bright colors. TIA for your advice. I've been receiving a lot of
priceless advice in this forum lately, and in a yahoogroups forum. For
which I am grateful.


From a standpoint - if you are going to paint the plane, it really
should be stripped first. There can be corrosion under the existing
paint that you will not see until it bubbles up the paint.

As a side note, if you try to sell your plane in the next few years,
anyone buying should be asking how the paintjob was completed, and if
you have proof (pictures/video) to verify it was correctly stripped,
etched, alodined, primed, etc...
