Dilunet and keel seals

[peacefulbliss]

I have just managed to scrape of the last 10 years of antifoul of my hull and plan to use dilunet on the remainer so that I dont damage the epoxy coating. Seems to work very well on a test.
I also want to remove the A/F from the keel seal and dont want to scrape this incase I damage the seal. Does anyone have experience of using Dilunet and know whether it is likely to degrade the keel seal? I not sure what it is but this is on a westerly Centaur.
Help/comments much appreciated.

You could try a small area as a test piece on the seal, I don't think it will harm it though.

Some members make their own using caustic soda & wallpaper paste.

Ref your keel A/F. If the Dilunet is applied in a 1/8" or so thickness, then covered with clingfilm, this stops it drying out, and as it's see through you can check progress.

It took 4 days in winter to soften 3 coats of hard racing & 1 primer.

If you can use a pressure washer it's so much quicker, not always possible in a yard

Don't know about your seals but, Dilunett has left me with some large and permanent holes in my forearm. I know, I know, it was my fault for not taking more care - but I pass on this caution so that someone can benefit form my tribal scars.

By the way, it did work on my antifouling-slowly.

Welcome to the forums !

I have found Dilunet so weak as to be almost useless, this was almost certainly due to trying it in cold winter weather.

I would certainly advocate using safety protection though, especially goggles, with boat undersides where one is looking up at the bit being treated.

My father had a Centaur, and I have friends with them.

Incidentally, a lot better sailing boat than it's usually given credit for, in the right hands.

There is no keel seal per se, just mastic, so I'd think as long as not coated in thick Dilunet for a long time and care is taken should be nothing to worry about.

These boats usually require a lot of internal reinforcement at the keels, Dad did this and used a huge spanner to tighten the bolts; a chum said his hull was similarly reinforced, but he used to tear his hair out as every time the boat was lifted a small gap would appear at the front of the keels.
