Hi Guys
I need some help please,my schooner is having its final coat of paint, the time was late afternoon in the garden, it had been raining a few hours before but the ground was dry, there was no wind, and bright sunshine, over a week the boat has had 3 coats of primer each coat rubbed down, and this was the last of the 3 coats of top coat, all coats of paint looked good, the finish prior to the last coat was smooth and showed the curve of the boat well, this last coat has given the boat what appears to be flats between each bulkhead you can even see where the nails were, there are no flats its an illusion, what caused it.  I have supplied a photo to show the effect

thanks Geoff

If the surface is flat there is something going on with temperature here.  I suspect you have taken the model from a cooler environment to a warmer one and the rate of drying of the paint has been affected by the heat sink effect of the frame behind the surface.  I'm sure a gentle rub down with a very fine wet and dry will restore an even surface.

I totally agree with Bunkerbarge.   Leave the hull in the area to be sprayed for an hour or so before spraying to ensure an even temperature and dryness throughout.

Hallo, I too had this problem with the deck of my Tug. It was planked with 1/4 obechi, looked great when the flat paint was ready to receive the gloss. When the gloss dried all the planks magically appeared, something to do with the tightening of the paint. The annoying thing was they vanished when cut back. No matter what I did it was futile and I ended up skinning the deck with plasticard,  Nemesis

Is that's Halfords matt/satin black?

If so then your problem is humidity, warm and dry weather is what you need. It's taken me by surprise before too.

Strangely it can vary between cans of paint, some can be totally OK while others go milky, if you spray over it will go milky again unless the previous coat is completely dry, a few days in the airing cupboard will do it. Alternatively a good going over with panel wipe before the next coat worked for me

Hi Guys
I have to say it again " this is a great forum", you gave me the answer I was looking for Bunkerbarge and Footski, I left the boat outside for a couple of hours to settle down temperature wise and then gave it another coat, perfect finish this time, it makes sense that the area local to the bulkheads would be cooler than the area between them, giving a difference in drying time, thanks to all who replied

A pleasure...

a bit more advice......

do not rush putting a top coat on it in the present humid/cool temperatures we are having at the moment

(hard to do i know)

the primer coats will remain "soft" and the finishing coats will keep it that way as they dry on top of it

if you dont... you will get a great finish now that will "sink" over the next couple of weeks/months  and you will end up re-painting it or loathing it


this is the bitter voice of experience!  not once but many times
