Hi, the rudder blade on my sportsboat came with a cover. Unfortunately, the rudder got damp while in the bag and now the entire blade is covered in tiny blisters. I need to refinish the blade but should I just sand it and then paint it or do I need to regel it?

Anyone got any good links to website/videos that show how to do this... Also what are the best products?

Thanks....

Wood, fiberglass, carbon fiber silly putty?

Paint, varnish, gel coat, or invisibility cloak?

need to know a lot more on what it is and what it is finished in....

It's fibreglass/GRP... It's a Laser SB3 rudder blade. I'm not sure what's inside but it's probably foam and glassfibre. The outside is bare white gelcoat. The blisters are very low and small.

I had a laser C board that had the same problem. The blisters disappeared when the board was left in the sun (supported evenly). I thought there would be voids to sand and fill ,but it looked good as new.

hmmm, sounds like it is product specific - try contacting the manufacturer?

Also how deep is thins stuff, this does not sound like any osmotic (sp?) blistering seen in below the waterline GRP hulls.
