I'm getting better at ding repair, but I find that the polyester is harder to work with than the epoxy ding repair kits.
Here's my problem- when I use the epoxy it turns into a nice workable slurry after 20 min or so and stays that way for awhile before it hardens. The polyester, on the other hand, goes from being an unworkable liquid to a hard unworkable gel in a minute or so. This gives me a very small window of time to apply the stuff before it hardens.
Here's the kit I use: http://www.amazon.com/Ding-All-Standard ... 185&sr=8-2
I follow the instructions for measurements but maybe I'm using too much hardener? Does anyone cheat and use less hardener?
Any damage to a surfboard, regardless of how small the ding is, will affect its strength and integrity.
The fibreglass in a surfboard is what creates and gives it strength, not the foam or blank of the surfboard.
Here's the difference between Fiberglass and Epoxy:
1 Traditional Fibreglass (POLY/PU) Surfboard Technology:
Poly or polyester represents a traditional fibreglass surfboard. PU or polyurethane foam is the foam of the traditional fibreglass board. The foam core is laid up with weighted fibreglass cloth and laminated with polyester resin. These types of surfboards have been around since the 1960s.
2. Epoxy Surfboard Technology (EPOXY/EPS or XPS):
These types of boards are becoming more prevalent and use polystyrene foam (two different types – EPS and XPS), both of which are coated with fibreglass cloth and epoxy resin.
