Title: masking issues
Post by: Trucker on October 07, 2018, 07:34:52 pm
after spraying my racing rc yacht i was quite pleased with the finish, but im left with small ridges along where the tape was, so, is it possible to remove the ridge and still keep the nice finish else where and have an even smoother hull...

With my limited experience I would advise the first rule is to not be hasty and let it harden for several days before touching it. Someone more experienced hopefully will suggest a safe way to lessen the ridge

I have over the years used very fine wet and dry with washing up liquid. Apply very gentle pressure on the raised edge.If your colour is dark this may leave light marks in the paint these will go when the area is varnished.  Someone may a better idea or method.

Is this effect caused by leaving the tape on too long? If so try rubbing with the chamois leather. It often works. nemesis

No I remove my tape straight away and still always have a small ridge applying high volumes of paint will not help. I let the paint harden then I use the method above and never had a problem but like I said earlier some one may know a better way.

Clean wet finger straight after application
and removing maskers.
Think it's in Stav's Paint Guide.
Tug Kenny thought it was good.
Once dried a different problem.

As Ned says, give it time to set up ( 5 - 10 minutes or so depending on paint) remove tape, let it sit for a short time longer, than using a wet finger with some washing up liquid on it for lubrication, gently but firmly press down as you run your finger along it.
OF COURSE WORD OF WARNING - THE TIME ALSO DEPENDS ON WHETHER YOU SPRAYED OR BRUSH PAINTED, SPRAYING MEANS THE TIME WILL BE CONSIDERABLY SHORTER.

Allways use 3m fine line tape for ANY area likely to get paint creep no other way regardless of anyone telling you it works for me Dont bother with the tamya tape load of pant compared to a few pennies more....remember one thing Buy Cheap Buy Twice or use the best and forget the rest,how do I know well simple 40 years in the paint trade

Thanks Dave. What width do you recommend? My models are getting smaller as I age ! I’ve tried 3mm Tamiya and backed that with ordinary masking, but as you say........
[size=78%] What I  really Struggle with is working the tape round the angular protuberances and maintaining a straight line from bow to stern. Do I have to cut the tape, put a separate piece over the chine/spray rail and then continue? Or is there a professional secret ?[/size]

I normally do it in one continuos piece...If you are struggling try using a laser level to get a straight line

For detailed work I now use Humbrol Maskol fluid, a brush on latex mask.

The Tamiya 2 or 3mm wide white tape is just pure crap. Don't bother trying in my experience. Nothing wrong with their other beige coloured tapes which produce an excellent result if used correctly. Never used it myself but from what I can see the 3M 2 or 3mm tape is their wider stuff slitted down, which in my opinion makes it 100% more considerable from the start.  Masking is all about thinking ahead anyway. Mask up or down for the curves etc, everyone has their own take, no 2 professionals I've encountered always use the same method. You can't learn this properly without trying first anyway.
