Spend ages prepping grp area on boat where a 3'' wide line is painted on.Anyway got rollers,blue masking,foam brushes,acetone etc ready to do a nice job.In the mean time my old man thought he would 'help' and i got there to find it not degreased and painted with cheap brush and free hand!! Bloody brush strokes etc. Don't want to upset him and paint strip it all so what would you do?Also really windy today so dust in it then it drizzled!!! I'm still fuming.
 
Sand it down then give it another coat; Toplac can take a lot of thinning, in fact definitely requires it in anything remotely wintery, so now the 'base coat' is on a thinned top coat should do the trick.

The lack of degreasing is a bit worrying though, good luck.

When Seajet says "sand it down", I am sure he wants you to use wetted wet and dry paper - something reasonably fine maybe 240/320

Seajet agrees that sounds just the job, in a perfect world maybe also with the aid of something like a drill with a rotary wire brush attachment. :)

I recently spent a lot of hours using a conventional h/h dril with a rotary wire cup brush, trying to remove paint build-up, and I recall it was the devil's own problem controlling it and keeping it applied just where I wanted - and not where I didn't.

For a task such as you've described, I'd be thinking in terms of a cheap Dremel-type rotary tool, with a much smaller and more easily controlled abrasive tool-tip or wire cup brush.

Try and get another coat ontop the base coat and see what the results turn out to be.
 
No-one mentioned a wire brush on grp, this is on steel brackets.

I find a rotary wire brush on a drill fine when one is used to it; the trick is not to press too hard.

I do have a rechargeable Dremel as well, used it on my boat yesterday to cut off a bolt end, very handy tool.

Bit of crossed purposes here! Mask it off and use wet and dry, wet on a rubber sanding block. You will find Toplac flattens down well. The block wil allow you to keep control over the area you are flatting. Hopefully the paint has stuck to the GRP, but if it has not then this method will loosen any flaking bits so that you can start again. Best if you put a coat of undercoat on first, lightly flat that, clean and then do one coat of Toplac.
 
Calm down, then repaint it, then thank your Dad, he thought he was helping !
And a little white lie that he damp / dust got in so you had to do it again
 
Comparative Value

You have an old man who is interested in what you do and wants to help you.
Do you know how lucky you are?
Yet it seems that you value quality of finish above that.
I think its your values that need refinishing - not your paintwork. After all even if you wanted advice , you didn't need to "dis" him and his contribution on a public forum.
 
^ :rolleyes:

My old man would never go anywhere near my stuff, he knows he's not very good at DIY thank goodness but he's not a sensitive soul and is big and old enough to know he cocked up if he did that to mine and I stripped it back off again :rolleyes:

I have just done my hull with Toplac, sand it back down with a rotary sander, degrease with No 1 Internationals and do it again if you want it right. Only takes a day, your only doing a small part not the whole hull. Top tip weight for a warm day, I did mine a few months ago when it was too cold, and flattend it down with a roller after all the bubbles that come up that seems normal with toplac after a few searches on here. Thinning didn't make any difference...

I just told him it needs flatting ready for its next coat . Hes just as bad with trailer and engine....no idea that boats are more specialist than his lawnmower.
Here are a few more examples-
'why don't you bring the other boat home on a trailer to save a grand a year on the pontoon?' (its 32' long keel and 6 tons!!!)

'well just use a car relay to save 130 quid from mariner' (relay is waterproof and operates more than one thing)

nav lights......don't even ask what suggestion was!!

Single wanted to know how to deal with the paint, not his old man.
I bet he has more than enough experience with his old man.

Oh. Do tell. Was it something to do with brake lights on a car?????
 
Wet and dry sands through Toplac nicely - personally I would start with the lowest number that really shifts the stuff, and work my way up the numbers....leaving a good "key" means don't need a 100% smooth finish.

Hide the paint tin until you are ready to do the job.
