I have used the white milliput for some time but recently saw a post (which I can no longer find!) about the advantage of the yellow over the white. Any imput would be much appreciated. I am about to use it to fill a large (1/4x 3/8 inch) whole in a fiberglass casting of the Ferrrari 246. I patiently await the experts : ))

The yellow Milliput's really good - tough, trimmable before it sets, sands well afterwards. However, I'd query its adhesive capability when trying to bond to fibreglass. Use P38 for the job - from experience, it'll stick the best to fibreglass ( or indeed anything else ! )

Cheers

White gives a finer finish, while yellow give a rougher finish. There's no strength difference. It'll never fill a hole like that and offer any strength once it's dry. Epoxy something behind like styrene sheet or wire mesh and then fill. It'll be fine.
