I did my first DIY repairs of minor chips on my hull in September and I agree: it was fast and easy. The chips disappeared. I used the SR "arctic white" purchased from my dealer.
Here's what I came away with from my first experience: There is no need to cover the repair with wax paper while the patch is curing, as described in some threads and instructions. Curing was sped up with a blow dryer. When adding drops of hardening agent, fewer drops is better than more drops so you don't cause pinholes in the repair from the heat of rapid curing. Also, fewer drops gives you the right consistency of material and gives you a little more working time. Lastly: I'll save a TON of money doing repairs myself in the future. Well, let's hope I don't bang up the hull enough to save that much money but there's no doubt in my mind that this is a skill worth having.
