[Zmagnette] Paint

[John Park]

Hi Steve, Does this latest missive mean more adjustments to your original
discourse on painting? Being an amateur it would be nice to have the
complete and accurate version so I'm/we're not open to mis-interpretation.
I really like when you "experienced" guys give a full detailed account of
how to do things. I'm trying to keep some semblance of fix it history like
Wray Lemke did for us back at GT35. Regards, John

ooooops, John is absolutely right.  I should have looked at my "cans" of
junk before writing such a treatise.  I now realize how I made that mistake.
I use to use PPG DP40 epoxy sealer, and an etching stuff prior to that (a
yellow/greenie looking product).   Somewhere along there, the guy I work
with said you really didn't need to use the etching stuff anymore, as as the
DP40 would be fine without it.

 

Then, to make matters worse "in my mind", I started using SEM and UPol "self
etching primer" in spray cans, again on the advice of the same guy, when I
would occassionaly sand through, or whatever, the epoxy sealer.  My "guy"
said that would be fine, and totally compatible with the DP40 type products
(I now use a similar type product,made by TCP (which I believe is made by
ValSpar, rather than the $$$$ PPG DP40, or even the PPG Omni line).  Thus,
somehow in the back recesses of the remnants of my withering brain, the two
products somewhat merged and became "self-etching epoxy sealer".  John is
100% correct, ain't no such animal.  

 

What I will say, is that on the last 3 cars (well, 2 cars, one large truck)
I have skipped the etching stage completely, and gone completely with the
epoxy sealer, as the first step.  Have not had one problem . . . again, on
the advice of a respected auto body supplier person.  Guess that is
partially how I derived the "new (so new, it hasn't been invented yet!)
product:  self-etching epoxy sealer!  Throw in the self-etching spray cans
of primer, which was recommended to use on whatever bare metal areas might
occur, and that completed my erroneous mental route.

 

The next time I attempt such a discourse, I think I best mosey up to my
shop, and check the cans of stuff I'm talking about.

I've never heard of " self-etching, epoxy - catalytic sealer ".  Always
thought it was one or the other... Either an etch primer, or a epoxy, not
both...  What product is " self-etching, epoxy - catalytic sealer "?  Google
gives me nothing.
