Hi guys i made tons of stuff in wrapping and first time in my life i layed on fiberglass piece carbon then cutted around and brushed to lay second layer- by polyster resin. all time very EVEthing was good but not after 2 days its still not dry???? wtf i thought as other parts ive done never beeen to that AND WHAT IS INTERESTING YOU BRUSH WITH PAPER THAT NOT FULLY CURED SURFACE WITH BLADE AND THEN CAN BRUSH WITH PAPER BUT MOST INTERESTING IF PART WONT STICK TO YOUR HANDS AND YOU THINK ITS GOOD AND PUTTING IN TEMPERATURE LIKE 25 ITS STARTING TO COVERT INTO SAME LIKE BEFORE 5 MINUTES LAYED SURFACE .

ANY CLUE GUYS? IF BAD HARDENER MIXING THE IN SOME PLLACES WONT CURE IF TO MUCH HARDENER BE THEN SIMPLY CRACK IF IF MISSING HARDENER THEN SIMPLY WONT DRY. BUT WHY THIS HAPPENED FIRST TIME? I THINK MAYBE THATS BECAUSE I WORKED IN COLD LIKE +9 PLACE AND MAYBE CARBON EATED CONDENSATE THATS WAY? AS NO OTHER IDEAS FOR MORE.

I CHANGED RESIN, I CHANGED HARDENER AND THE SAME.



YOU KNOW GUYS THATS NOT EPOXY THATS NEED TEMPERATURE IR POLYSTER THAT ALMOST NO MATTER AND EASY TO WORK WITH.

man i putted near my heating thing for couple minutes resin started to go like bubbles so definitely overheated. one part cured for no tacky surface 3 days unreal. i tryed esterday to lay one layer when was plus 15 so lets see today. my main scary thing from me is i hope carbon not got condensate before i layed it.
