And there I was thinking I was a natural deck filler changer
I best remove it and get the 3M 4200 so I can take care of the last knuckle. There is what appears to be a tiny hairline crack in the non-skid stretching from one of the screws and about 10mm inboard...should i bore this out and do an epoxy fill job while I'm at it?
I read that 4200 forms a permanent bond - will I be able to change the cap in the future if I have to convert back to holding tank? No facilities for pumping out here in South-East Asia but in case I wanted to head for Australia or something it might be an issue that I don't have a tank...
Thanks again for the advice SD, it's very much appreciated.
