If you've made basecoat then first of all; well done. Its pretty hard to do that lol.

Basecoat needs to be put on as light steady coats. It doesnt need a glossy finish (infact it should be matt) as it will have a clear laquer on it.

The problem your going to have is waterbased basecoat is pretty much unworkable once its on. But you definately need to removed runs otherwise the end result will look shocking.

Try wet flatting the runs out with 800-1200 although I think your basecoat will just go mushy and make a mess.

Also this weather is way to cold to be spraying, needs to be warm (not blistering hot, but a nice day) or else the paint will bloom.

I did this a while ago and recieved some much appreciated help from Jack and Peter(plus others)

Have a look at this

Water based paint doesn't need to be warm however it needs air flow.

The laqquer will be 2 pack so usual rules will apply

Hope this helps

just to add... depending on what colour you have when its sprayed out it will look a different colour and wil return to its original colour once it is through dry.
The first time i used waterbase was on my VR6. Dragon green when sprayed look dark metalic blue! untill you apply some air either from the spray gun or blower, imagin the shock and horror!

Max Mayer is Top stuff too.

Yeah thats true, it always looks a funky colour in the tin and if you put it on wet, but it does return to its proper colour!

This is hard to use if you dont know what your doing ive don it a couple of times.
Dont know if anyone else has done this but what i had to do when i got runs in it which is easy when you dont know how waterbased paint works
is to take the whole lot back off let car dry out light grey scothbrite over with a bit off water let dry out remask and do it again.
Like these peaple say above spray light coats then press gun trigger in slightly just anouth to relise air let it go to the matt finish and apply again keep
doing this till the area is covered let dry in booth for 15 20 minutes then spray your laker on.

P.S Hope im not wrong about this but i did used to use the stuff day in day out mixing this is not the easiet of jobs either.

Id say your right.

Although the basecoat doesn't need to be baked before laquer. As soon as its flashed off and dry to touch (somewhere inconspicuous, like the masking) you can start and apply laquer.
