After the rub down.

As you can see the hull is now totally flat, and the boot topping line is pretty much part of the hull with no ridge, there are a few tiny spots along the line where it is a little raised but those will fill in over the next few coats,

I’ll now go and finish the boat in thin coats until I have the surface I require for a good polish.

It wasn’t that much work, took about an hour with some 1000 grit and water to clean up, I’m glad I attempted this now as doing it earlier would I expect resulted in rubbing through the paint, here I only had one tiny spot of rub through at the bow to which a paint brush and a drop of paint sorted and I sanded that back, feathered into the hull and you now can’t even see where this was.

It’s slow progress but it will pay off in the long run, this is the first time I’ve attempted to coat a finished painted surface on a boat with this varnish,( first attempts were on stands to which I had good results for trials) so going slow and steady and learning by what I can and can’t do is paying off for a good finish.

I’ve used this on deck work countless times but varnish on bare wood is much more forgiving for a sand though mistake where as on paint removing the paint is a disaster.

Overall besides the amount of work and time it’s taking I am confident for a decent final finish to the hull and pleased on how it’s turning out.
But you know what they say “slow and steady wins the race” and in this case slow is working well although I’m having to fight my usual impatience!

On a side note my Mrs gave me one of my birthday presents early, it finished my Star Trek collection off nicely, although I know she overpaid but totally worth it, now I just need to find a shelf big enough for 140 star ship models!!!

Things were going so well...

I guess my little paint repair didn’t feather in as well as I expected...

As you can see on one side of the hull perfect, the other in the 2nd photos  by the bow now shows a different shade of light green where I thought I had fixed the little rub through!

To say I’m disappointed is an understatement given how much work I put into keeping the hull tidy,
This leaves me with one option, to mask up, sand down the light green and respray to get an even colour on the top half of the hull, it’s a days work added to current this difference In shade to which will have to wait a couple of days now while I wait for more tape to arrive in the post.

Frustrated yes.... heavy handed yup....

It could be worse I could have to respray the whole bloody boat but it’s fortunate I only have a single colour to do and this time I hope no mistakes....

Not a costly error as I still have a couple of pots of the colour left for such an event but annoyed about this over a single little 2mm white dot to forcable respray half the hull to correct the shade difference absolutely, my only assumption is that the repaired area was sprayed onto the epoxy coat and not to the base primer has kept it from turning the slightly darker colour that it was on the primer, only good thing to come from this is that repairs later to paint work will avoid having an entire hull respray to correct a patch that’s not quite the right shade as now any paint on top will be the same shade all over as the epoxy will be below the paint work and then above...

What can I say shit happened... and it’s not the first time paint work gives me headaches, oh well a few days on the grinder and be good as new...

I was almost tempted to omit this from the blog but I do like to be honest even when I make a mistake... No





After I’ve fixed this mess I made I’ll revarnish the hull to seal it all in, give it only a few coats and just buff it up and avoid a glass finish and just go for a decent gloss shine.

My options are limited when forced to a repair like this it will still be a nice looking boat and the finish will still be excellent although just not as good as the deck.

What can I say I only have myself to blame and I’m kicking myself right now about it.

Well this is the extent of the damage on the light green I’ve sanded back flat and almost to the paint in some places, as you can see from the photos how bad my issue was, I did avoid sanding below the boot topping as the dark green is pretty good but also had the thicker layers of epoxy due to the way the boat was varnished

The damage isn’t that bad but these 3 patches show the extend of my injury to which I can only repaint the light green till it’s a level and even colour surface once again.

It is annoying and most my own fault being a little careless with how mi h pressure I used during my sanding, the good news being from this it’s given me an opportunity to reduce the paint build up under the decks rub rail, fix an off patch of paint on the far top side corner which was there from day one but I ignored and finally repairs later now will be of the same shade as the paints hitting the epoxy and not the base coat so this I hope will allow repairs later without this being done again.

However I was surprised how quickly I got the boat back to flat and ready for paint showing at least should I be forced to do this again it only took me an hour to pull it back and a day to come to respray, and back to varnish.

Overall it’s a mistake of my own doing for something as simple as to much pressure and another lesson learnt, but like I had said before this was my first time epoxy varnishing a painted surface to this extent and shape. so I’ve learnt a lot about what not to do.

Although it feels like 10 steps backwards in reality it’s a days work to fix to which in the grand scheme of things ain’t that bad for a mistake correction.

Anyway I can’t do anything else for a few days while I wait for some more masking tape ( I ran out redoing the rudder) but it will give me time to cool off from the boat and plan ahead a little clearer.

When it comes to resprayinf I’ll put as many coats on until I have that level uniform colour, and I’ll feather the bottom edge into the boot topping every coat to reduce any build up as this issues was a used by trying to bridge the boot topping to start with!
In any case should I get a ridge line during the varnishing, I will simply light sand it as flat as I can and live with a ridge line, I’ll also not attempt to get a super mirror finish, instead just go for the much simpler high gloss, it requires less varnish, less work and this time I know less chance of mistakes because if this happens a 3rd time I’ll just cry lol!

Respray of the top colour in progress..

3 or 4 coats should even all this up, I’ll know more after a couple of coats during rubbdowns if any odd colour patches appear.

All I can do is keep going until I’ve got the even coat, then back to varnishing.

4 coats later and all fixed, just needs a light rub down and I’ll put a coat of varnish on to seal, then attempt to carefully feather the mask line a little, should be ok now.
The paints still wet so forgive a couple of the photos as they look like the surface is all over the place but I can assure you it’s dead flat and smooth!

First coat of epoxy was laid on the new paint, I’m going to layer up the new paint with 4 coats over two days and give it a super light rub down then I’ll go back and finish the entire hull, I’m just rebuilding layers up right now, I’m also going to only light rubband flecs of dirt from the hull rather than doing full rub downs to avoid another incident like this, I’m also going to go up as far as 15-20 coats to be on the safe side to reduce rub throughs and that should polish up to a great shine, I’m just going to avoid a full mirror finish on the hull as the rub downs between coats to achieve that sort of finish is risky and although I avoided a mistake in the first 5 coats it’s was the 6th that clearly cost me a respray.

Again some trial and error using this as a hull finish, and in future I’ll just laquer a hull as this is a lot of work for very little extra payoff in comparison.

Lesson learned but unless we try these things we will never know the limitations of materials nor push our hobby forward.

I’ll keep you posted... any further issues and I expect I’ll rub down the entire hull, respray and laquer. I’m hoping to not need to go there but that’s my contingency plan for another mistake.

But fingers crossed this time.
