Well that is encouraging and since I glued up a project last night I'll
let you know how it went in a couple of days.

But it's a good idea to sand the surface of the old epoxy first.
That will remove any amine blush and roughing the surface will also
give the new epoxy a bit of bite.

If you lay new resin on resin that is less than 24 hours, no problems.

If you wait past 24 hours, the existing resin may develop an amine blush
which is easily removed with a ScotchBrite pad and water.

I always sand the old resin with a 24 grit disk before laying new resin
on top of old.

Though of course... epoxy does not dry, it hardens.

I roughed it up quite a bit before re-epoxing so the epoxy should bond
alright... I hope ;-)

Epoxy is great stuff . I was wondering if a non-toxic variety of epoxy
has been developed yet ?

In addition to these, there are many non-toxic epoxy coatings.

Food-Safe Adhesive
A two-component, low-viscosity EP48 epoxy has high strength and good
electrical insulation properties. It can be used to seal and coat metallic
and nonmetallic substrates and conforms to Title 21, U.S. Code of Federal
Regulations, FDA Chapter 1, Section 175-105 and 173.300 for food
applications. The epoxy has a 100:75 mix ratio and is 100% reactive. It
resists chemicals and prolonged submersion in water, dilute acids,
alkalines, aggressive organic solvents, ethanol, isopropanol, mineral
spirits, and gasoline. EP48 has a Shore-D hardness of 70+ and a tensile
strength of 5 kpsi. It is available in pint, gallon, and 5-gallon kits.
