<DIV><FONT face=Arial size=2>To Rodger,Diane ,Terry and =
list</FONT></DIV>
<DIV> </DIV>
<DIV><FONT face=Arial size=2> Thanks for those of =
you who
recently responded to my query on plate finishing ,sandblasting and
such.</FONT></DIV>
<DIV><FONT face=Arial size=2> After sandblasting a =
rusty Mason
A plate that also had a automotive finish gone astray partly do to =
technical
difficulties on my part, I was able to build it back up with a rust =
inhibitor called por-15. I followed this with a tie coat primer of =
the
same brand. Both of these were said by the factory rep. to be =
compatible
with my usual applications of acrylic lacquer sanding sealer and clear
coats. They were not! As I was building up the sealer I was =
starting to get some slight crinkling of the under coat(tie coat primer) =
Which
by the way is a high tech new fangled polyurethane coating.The thinner =
was
penetrating and causing a problem which was not supposed to be
possible.</FONT></DIV>
<DIV><FONT face=Arial size=2> Wanting desperately =
to save all
that hard work you all made a completely logical suggestion to seal it =
with
shellac. I thought you all were brilliant . Shellac has completely =
dis-similar solvents. I did a final sanding of the sealer ,which =
was no
really smooth ,and applied the shellac. Let that dry 8hrs. in 100 degree =
heat(calif. style) and then resprayed another final coat of the sealer =
and every
thing is flat and smooth,ready for the gold and clear =
coats.</FONT></DIV>
<DIV><FONT face=Arial size=2> In my last =
post to Diane I
had said that some times sandblasting is necessary to remove original =
base coats
gone bad. And as things go I just started on a stwy A plate that =
has had an
after factory coating(cheap paint job of unknown origin) that =
brittalized
everything done to the japanning( the black under coat) I have scraped =
much of
it off (instead off blasting) off in an effort to save the =
japanning. Some
times there just ain't no easy way.</FONT></DIV>
<DIV><FONT face=Arial size=2> So I will scrape sand and =
seal with
shellac then primer and sand till smooth. Thanks for the
help.</FONT></DIV>
