Spraying Two Colours - Problem

[Callist]

I was thinking of trying to spray two colours as mentioned before, however.. slightly different than which I previously mentioned.

I want to have two colours split with no gap, i.e. the petrol tank, upper half one colour, the lower half another colour. How can this be done? Do I simply apply the special tape and mask one half of the tank and paint one half, then remove the tape and try to apply the tape perfectly against the newly painted half and paint the second half? The issue I can see here is possibly misaligning the tape by 0.1mm or such and getting a horrid little gap or paint overlap etc..

Whats the general way of going about this?

Thanks.

Would it be an idea to feather the paint furthur than needed and then apply the tape and second paint colour?

usually the tank would be fully painted with the lighter colour then mask off the part to remain that colour and paint with your second

and as with the previously mentioned method with the 'stripes' I would simply just make use of the lacquer to get rid of the ridge?

- Would I spray a little heavier near the 'ridge'?

not really just build it up with several coats it should level out

As snooper said, 3 good coats will see the edge gone, a flat and polish after and it will look like glass

Another thing - I've never really needed to spray over a repair before, so I do not know the Primer drill here.

I have a panel which has damage to it and requires some filler. How far back should I sand the paint when applying the filler? (It's a fibreglass body piece for a motorbike).

Secondly, would I need to primer over the repaired area only? If so, what type of primer and how much?


Thanks
