<p class="MsoNormal">Hi all,</p>
<p class="MsoNormal">I use <span class="spelle">Paraloid</span> B-72 to repair shells that have been broken, and to prepare shell surfaces for labeling in cases where the material doesn’t hold ink well.
</p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">While the repairs it makes are beautiful (often I can’t even tell that the shell was broken in the first place), a great frustration of using B-72 is how messy it can get, and how quickly the solvent evaporates (which changes the concentration).
</p>
<p class="MsoNormal">I have the resin pellets and mix up new B-72 in acetone, and currently we apply the B-72 with little brush-bottle applicators supplied by University Products with their pre-mixed paraloid.</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">However, it only takes a few uses before the threads on the brush-bottles get
<span class="spelle">gunked</span> up, requiring acetone and a lot of grip strength to reopen.
</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Is there any clever solution for this?</p>
<p class="MsoNormal"> </p>
<p class="MsoNormal">Also -- has anyone tried “fineline applicators” with b-72 before?</p>
<p class="MsoNormal">Best,</p>
<p class="MsoNormal">Nate</p>
