Seeking H&E stains procedure for Ground Plastic section

From:Bernard Ian R SSgt 59 CRES/MSROP

Hello again, to all fellow, Histo Plastic Researchers,
                                                    My Pathologist is adamant in me, finding a H&E procedure that will work, to stain some plastic processed (Methyl Methacrylate) pig & rabbit eye implants.  I mentioned to him about other stains out there, that work similarly to the H&E and stains better.   However, he insists that the H&E will give him a familiar and better contrast.
The one method I have, worked (acceptable to him) for another plastic procedure( A Butyl Methyl Methacrylate), but not this one.  The stain came out to light.  I even restained the slides following the same procedure again.  And it still turned out light.
My adopted Plastic H&E Method abbreviated to key reagents:
1. I surface etched the plastic slides before staining to allow for stain penetration in 1 % Formic Acid ( 2 mins), 50/50 ETOH and rinse in Distilled H20.
2. Stain 6 min in Harris Hematoxylin
3. Differentiate in 0.5 % Acid Alcohol ( HCL in 70 % Alcohol)
4. Blue in Ammonia  water (12 drops Ammonium Hydroxide in 250 mls Distilled water)
5. Stain 1 min in Eosin Y solution
6. Dehydrate to Xylene substitute.
These sections are less than 100 microns thick, no less than 40 microns
I need  help with a good procedure.
Thanks in advance
