First, Please follow Korey' instructions and view the How To Videos. In that case I'd reccomend you to watch as much footage as possible. Generally Delta Kits.
You can find a lot of them on
www.youtube.com or I beilieve I have watched some on their website
www.deltakits.com
Its puzzled me as to a few questions:
Check how much resin you are using both "Bond & Pit"
Each time you perform a new repair, be sure to use a "New" razor blade!
Are you buffing the pit with "Pit Polish" this along with a "Clean" shop towel
Typically clears up the "Cured" pit resin.
Always be sure to do a "Full 5 minutes Cure" UV Light
I wouldn't depend on "Sunlight"
Just some thought!
