Thanks for your post. You are right with your advice.
I am convinced, that there seems a concept or idea, of "thick is good" and works better.
But those thoughts are unfortunately not correct. You only need enough Hi-Tek film to separate bore and alloy during resident time inside barrel.
As I have said many, many, many times previously, if done correctly, one thin blotchy coat should work. Second or additional coats, simply improve cosmetic appearances and should cover most imperfections left with thin first coat.
For some applications, a third very thin coats may be required, but that is not the norm.
Looking at it another way, if first coat fails tests, don't bother to re-cook, it wont fix adhesion failure problems, as coating will not re-activate and bond to alloy with additional cooking.
Do not then re-coat, to try and fix bad first coat, as applying second coat, wont fix first coat failure problems.
I am wondering now, after having seen this sort of problems arise a few times, if may be I should have suggested a 10g/100mls mixture, to be used as a primer coat, using the same 6mls to 250 bullets as the first coat.
Then, after all is OK with this first coat, user then apply the 20g/100mls as second final coat.
My reasoning is, that if first thin coat bonds OK to alloy, and passes all tests, then subsequent coats will bond to previous bonded coat, and finish would be functional, and finish would be also pleasing to users eye.
