Epoxy that stays clear

Hello - anyone have a line on epoxy that stays clear when dry. I have been using Tower Build It 30 min and it yellowed soon after curing.

Any suggestions woudl be great, thanks.

I use BobSmith brand, not sure of the website. He's in RCM this month though. It stays very decently clear for a long time. You can still tell it's there, just not that old looking yellowish ick. Makes for some nice looking fillet work.

30 usually stays clearer than say 5 or 15 but jsut in case , you know that alcohol will clean it away before it dries so you dont need to worry about it yellowing.
