Project Y EP 16 

Glad you like it! thanks for the comment

thank you chris. I do believe now that it was probably the dew point setting in too early in the curing process. well hey I learned something new . thanks for your comment

thanks

say what??

I wish. :)) but one day I'll make it to beautiful Spain. for sure!

Wauw, uw vader maakt er echt een mooie boot van!👍

Thanks 👍. as some people suggest here , probably the dew point set in too early in the curing process. well hey I learned something new today...

thank you very much for your in-depth view on the situation. I fully agree with you and believe that this is indeed what caused the problem. strange though that some bits did stick well, and others didn't....

@@BoatProjectY I've worked with paint for over 48 years, first as a development chemist and for the last 32 years as technical manager. The one thing I can say with confidence is that adhesion failures frequently are patchy over large surfaces. Sometimes this is due to poor preparation and cleaning (especially in inaccessible areas), equally it may be down to small environmental differences (if you have a small hole in the cabin you may have better ventilation in this area, or it may be worse because any heat you have generated will leak quicker from this area). Another factor that you may not have considered is film thickness. Paints are designed to work at specific film thicknesses, in my limited experience with the paints I have used on my boat, they are usually quite forgiving (50-100 microns per coat). Excessively high films, particularly with single pack paints, will slow down the drying as they need to absorb oxygen from the atmosphere to dry. I expect that your areas of failure may be down to a combination of all of these points. My advice to customers in a similar situation is to go back to basics and follow the data sheets for the paints meticulously. Once you are having success you can try to make small changes to suit your specific application. If you make the changes one at a time and you then get a failure, you can go back to your previous method and if it works you know the cause of failure. In temperatures below about 15 deg C, I would recommend that you monitor the temperature & relative humidity, especially if there is a large difference . You can get a digital thermometer/hygrometer online for 30-40 Euro's which will also record min/max temp & RH, so you know how low they drop over night. At this time of year you may find some large differences! Good luck with the rest of the refit and keep posting the video's, I enjoy the way you present them.

the topcoat is not needed for this underlaying structure I will add isolation to it later, but wanted to protect it for rust. but I guess you're right. I should have sanded it first.

hi ben, I've done this before with great result on another parts of the boat. but as some people suggest here , probably the dew point set in too early in the curing process. well hey I learned something now today...

I can not agree with you more. I think the dew point set in soon after we finished. stupid, error on my side, lots of extra work but I hope I learned something from it. thanks for your comment

@@BoatProjectY No worries, keep up the good work, its looking better with every video.

@@alexneville4394 sometimes you gotta look very hard, but yes overall it's going forward...., thanks again

merci , je pense en faite qu'il faisait trop froid et trop humide cette nuit la. dommage mais j'ai appris qq chose.
