Refinishing with Water-Base

[Farrell]

Thanks for your reply Jon. I talked at length with Mark Ellis, Enduro
technical representative, and explained my procedures. I let the sprayed
finish cure/dry for three weeks with good air movement and 50% humidity
before wet sanding. He indicated that wet sanding after that length of cure
under those conditions should cause no problems. However, your point is well
taken - obviously something is going wrong - and I certainly don't know for
sure whether it is my procedures or the products I am using. Unfortunately,
after I spray on the Pianolac, I will be wet sanding with Arthur Grudco's
wet sanding oil - so a direct comparison will not be made. Well, strike
that. I will also paint a test panel with Pianolac and wet sand it with
water just to see if the Pianolac performs better than the Enduro - just for
the yahoo of it. I'll let ya know how it works out.
