Chris, i have that forum bookmarked great info.
snake, i am not repairing one section, i am doing both quarters at once. I have yet to get to clearing the base.
I have spent the day cleaning things up and repairing the blisters. two coats of primer letting everything get good and dry, hopefully this works else i call the wrecker..........errrrrrrrrr

Sounds to me like you're painting in too cold of temperatures.
To pull that off with no worries, you need to wait 3 times longer before coats.
You're shooting the clear too soon IMO, too much solvent trapped.
It gets hard before the underneath has cured enough.
The fact that today's materials in the US aren't worth a damn, doesn't help either...
Thanks EPA for that!

Are you painting over any body work. IE bondo or such. I had a problem with blisters when I painted over a spot on my exploder and I think I tracked ti down to not having it mixed properly or not letting it set long enough before covering it with paint. At least that is what the paint shop thinks.

+1 we need pics of this.
there are numerous reasons the "solvent pop" from recoating too quick. forgetting to use the wax and grease remover etc.
pics please. you might need to let the paint dry for a few day to cure before proceding.

Ok i sanded the spots down, two coats of primer, ill block it to today and shoot it again. primer has set for 24 hours but now the weather has turned against me (down right cold). I have to get this right today, am i missing something?
BTW i have yet to re clear so i think i can eliminate that, mix ratio is 1-1 so i think that can be eliminated as well

What kind of heater are you using?
A kerosene or diesel fired heater will deposit hydros on the finish which WILL cause lifting. IMO, even a propane fired heater has the potential to deposit crap on the car if the mixture is not right.
Also, just what layer is the blistering happening? (ie: between the base and clear, between the first primer and metal, etc.)

i was using a propane heater only before and after applying coats. Blistering is occurring immediately upon application of base coat, paint pops right off the primer or so it seams.
on my last application the blistering appears "around" my repair and in another spot in the middle, this time i its a crackling effect rather than blisters the size of a soft ball as in the last few days.
