Pinholes in Primer Sealer

M

mjsorl

Just finished putting the final coat of the epoxy sealer on and I have a case of pinholes and small itty bitty bubbles.
When I sprayed the EP reduced (slow reducer) 1/1 50%, the temp had pushed to 88 to 93 in the hour. Humidity it's Florida.
Compressor set at 145 / 115
Desiccant filter / oil and water separate prior to Desiccant
Devilbis millennium gun 1.4 tip
Gun set @ 31 psi at the gun 120 on the line, ⅜" hose and couplings.

And I have these tiny pits and bubbles. Primarily on fenders and tops of the doors, it's a convertible and I have the hoods off.
This is the corrective action I have taken: Sanded body with 320 / spot filled all of the holes and resounded with 600, then went to 800. I believe I am ready to put the base on after I do a thin light coat of Epoxy : activator : slow reducer 1:1:1 wait 24 and sand and apply the base.

Any help would be appreciated.
 
Pinholes must have been there before the sealer went on, the corrective repairs will work, shoot another thin coat of epoxy and shoot your basecoat. Denib the base between coats if needed.
 
Changed out the descant filter
Sanded down the fenders with 220 wet, 320 wet and then on to 800
Degreased
Mixed the Sealer and added ur 70 ( good for 100 degrees +)
Temp at the time of spraying the sealer 88, gut set @ 31 psi shortened the pattern
Finally a very happy camper.

Thanks all for the feedback and help.
Will continue to update
 
Did a quick touch with 800 wet prior to applying a tack coat and a wet of base, have some issues with lines, not sanding lines as per see but the edge of the pad making an issue, waited about 4 hours and did a minor scuff with a red scuff pad wet and will apply the final 2 coats wet in am.
