How many hours do you want to spend to find out that your 'great idea' was
an engineering rathole and that your time and materials have been wasted.
There are a lot of people offering advice here and the reason that people
keep coming back to specific things is that they have been tested by the
community and have been found to work the best.

MMC's, specific coatings, designs for spark gaps, etc...

He probably does but I would doubt that he makes a lot of money off of it.
This is especially a factor considering just how many gallons of other
paints / varnishes / coatings / etc... he probably tried out before he found
that Dolph's worked the best.


I would hate to see the number of 5-gallon tubs of very expensive stuff he
has with just a couple pints taken out and a faint "Oh Snap!" still hanging
in the air.

Or by watching other people doing the same thing and learning from their
mistakes.


Set RANT=off
