RE: Radtek Powerboats 92

Wow nice build. But even at reg carbon prices of 41.00 - 47.00 per yard 2k seems high. The hybrid is a nice touch 38.50/ yard. Maybe all the clear coat is big $$$.
Hanspeter still getting 90%...

RE: air restriction

Sounds alot like the old offshore race boats. They used too get out of sight and dump the hatches to let the engines breath. Probably is warm intake air boggin you down.

RE: what went wrong

RE: How to seal a wooden boat? (many pinholes)

If you allready have bondo, try "watering it down" with resin for a more spreadable putty. It'll cure like reg bondo, just a wee bit harder to sand.

RE: what went wrong

Cool temps can create a slow cure. If using laminating resin (no wax additive) the sticky is awaiting the next laminate. Warm it up and let it cool before trying to sand again.
