BINGO...
That is enough to get me rolling once again (literally)...
Thanks Brad.

Yes on the 606 and 610 hardeners... I will scotch bright wash and put the cloth on tonight. In the AM, after another wash, the fill coats begin. (Assuming the washing is necessary if after only 6-8 hours.)

The bubbles are mainly surface. I will try to remove them first.

: Tim,

: If you are useing RAKA 127 with 350 slow non-blush hardener, you can put the
: fiberglass on as soon as it's tack free. If you can get your shop to 80
: deg and let it fall to 65 deg but not get colder than 60-65 deg, you
: should only use the 350 slow and forget the 610 fast.

: If you are useing the 127 Resin with 606 AND 610 you should wash first as
: RAKA's web site says "Our two to one mix ratio slow and fast
: hardeners are easy to use, are low blushing and can be mixed together to
: customize working characteristics and cure times." Anytime you have
: blushing, you want that off the surface before the next coat.

: Also, if you are putting on the next coat under 72 hours, there is no need to
: sand, just wash with water.

: Are the out-gassing air bubbles on top of the surface or are they just small
: bubbles in the previous coat? If you do have bubbles on top of the
: surface, wash first to remove the blush, then you can sand lightly with
: 150-220 to remove the bubbles.

: Generally, you want to put the next epoxy coat or fiberglass with epoxy on as
: soon as the last coat is tack free. There are different times with
: different epoxies, but I used RAKA 127/350 NON-blush on the last boat and
: it was tack free at 70 deg in about 6 hours.
