speed clear and polar is it needed?

#22
well my first experience with speed clear started out bad...i was worried about heat..when i should have been worried about the idiot holding the gun LOL..bumper temp was 74 degrees...the first coat i put on like i did universal real wet and flat looked great then right back with the second coat the same way...thats when things went south it started to sag and run in about 5 spots..i guess my mistake was i sprayed like i was gonna let it flash and just went too heavy and then i relized to late i had the gun set at 30 psi...in which i remembered my devilbiss plus likes 40 psi to spray hs clear.well that was friday...after i wet sanded out the flow indicators.repainted the spots where i broke thru . today i got the shop nice and toasty mixed up 10oz with a half part of medium reducer just because i thought i had the shop too hot for the fast activator....anyway i set the gun to 40 psi and i moved a little faster than normal..it turned out awesome this go around with one slight flow indicator and a litttle trash from 3 wasp making out in the ceiling...easy fix... and i loved i was able pick it up and move it within 20 minutes after spraying....now on to the hood...need to get a can of wasp killer first:)....ready for more suggestions from you guys where i may have gone wrong ..... thanks for all your help so far!!!

If you're using a Pro-lite, 40 Psi is way too high. I'd suggest starting over with the gun set up by following Barry's protocol that's in the manual.

hello thanks AAE i have a devilbiss plus gf670 spraying with a 1.4 tip and at first with 3 1/2 turns out..and then a half turn in the second time..so do you think the 40 psi was compensating for too much fluid?? and yes i will adjust according to Barrys procedure and see how how it goes...thanks again.

I don't know that gun. But, yes you may be compensating. Most new guns don't need over 30.

ok i sprayed the hood today with much better results...after following Barrys adjustment procedure...clear appeared to go on thinner as before it looked too heavy...but i didnt mix enough this time and way too much when i did bumper...anyway the hood flashed about 3 minutes before the second coat...and i noticed after it set up about an hour that where i started the first coat looked like it died back some..but the wettest part of first coat looked nice and clear.....maybe that 3 minute flash on first coat did that ??? idk.. the DBC base flashed about a hour and a half before clear.but i am highly satisfied how it layed down..other than a lil trash i will take care of that tommorow hopefully.thank you all again for the great advice....

the first coat looked pretty even...thats when i looked in the cup and realized i was gonna be short...the hood has same texture all over...just one side of hood had maybe 30 to 45 second more cure time than the other plus the 3 minutes of flash (thats not recommended) to mix more clear...lol just got to get the dummy holding the gun better organized
