Careful with a pressure washer. An electric pressure washer or a very wide fan from a gas washer is great for taking the foam out completely. Gas washer with a narrow stream can cut a boat.

Was hoping to find an alternative to sanding... Just need to buy more beer and embrace the carbon/fiberglass itch on my arms.. =/

Buy the extra backing pad set from H;F. When you run out of those pads (and they go quick), sand off the hooks and use regular sand paper and either super 80 spray adhesive, or contact cement to secure them to the disc (see the mini da on the left).

I agree, but to a certain extent. It depends on which air tool. I do almost all of my form shaping with a DA and 40 grit pad. It's all about controlling the pad speed. The only time I use a block is when I'm blocking a surface flat. I do think it's somewhat of an art though. Kind of like those guys that make ice sculptures with a chainsaw. I would say air tools aren't good for doing small, high detail jobs.

The pics do not do it justice, but there is so much glue and mountains of hardened resin in the corners, ontop of the carbon and along the firewall of the ski I still need to grind out...

Picked up the smallest 90 degree die grinder I could get and some flap disk wheels! Making things go much quicker!

Had some more fun today. So anyone have any guesses why there is foam blocks all over the inside of the ski? Filler? Or maybe used for shape? The engine bay and the sides of the ski go like this:

Resin | Foam | 1 sheet of very poorly laid carbon...




It is normal to be able to rip out the carbon right? :(

Can I reuse this?

Yeah I think it is gel coat.

Is it foam like this: http://www.fibreglast.com/product/Vinyl_Foam_4lb_Density/Foam

If so, it could be a foam core, sandwiched within the composite. There's almost no way that the gelcoat is the only remaining layer, gelcoat is similar to paint, it's just a surface layer that is extremely thin and doesn't offer any kind of structural support.
