either that, or I have scabies!

I said 'polyester' as the glass seems far more likely to get in your skin when rubbing down polyester-glass, rather than epoxy-glass, when it isn't so bad...

Of course should all be avoided...and I should be wearing overalls....but hey the sun is out.

Nearly done now anyway. One more paint....one more rub-down and we should be there.

I hope not to sound to 'elf and safety' but - really - glass fibres in the skin may be bad enough, but I hope everyone wears a face mask when sanding GRP. Once those fibres are in your lungs they never come out, and they will do a lot of long term damage....

Alternatively, if its hot anyway, you can use wet and dry (wet) and the fibres etc are just washing away from you then. And the water cools you down!

agreed!

facemask.....normally if it is a big job, yes, but not for a small bit of hand-sanding.

Under water.....again, I like to use wet'n'dry for later stages, but when you have to remove about a kg of excess polyester/glass you need a grinder. Unfortunately, I don't yet have an air-grinder and don't really want to use my bosch electric grinder under water :-)

Strangely enough, I got more itchy from the hand-sanding than I did from the grinder-sanding, maybe the grinder threw bigger chunks which are not so itchy.

Only one more big session now and then it will all be wet'n'dry in the shower.

OK, which of these actions would go down best in your home?

Heating a Ducati 350 crankcase for 30mins at 180C to get the bearings out...

Taking an hour in the shower while you wet and dry a set of IC foils...

From a woman's viewpoint:
Since I pay the electricity bills, the winner is the crankcase heating as long as it was done on the (yet-to-be-installed) workshop stove :D

mmmmmmmmmmm,

but if I told you that I then took it out the oven, found it was too hot for my gloves and dropped it on the laminate floor, forever melting the shape of a Ducati crankcase in floor.....

what then?

I used to teach at a school where a cook, on his day off, was cleaning his motor bike chain by soaking it in petrol. Seeing it wasn't doing enough decided to heat it over the gas stove.....burnt the kitchens down. Well the school food had always tasted awful anyway.
