1) wet sound the metalic paint (with say 1200 grit) some say yes, some say no
YES,
KEY the paint, or your clearcoat will slide off.
but this is a frame your painting,right?
the process your describing is usually for fairing panels etc.
for frames, powder coating is usually preferred.
but seeing as you have went to the effort of using etch primer etc, might as well finish it off with a clearcoat. again, if you dont key the paint, your lacquer will slide off
Next step the clear coat...here's the problem:
what the best way to cleat coat using aerosol cans
1) all in one go...one thick coat NO
2) build it up layer by layer YES
again, the process your describing is usually reserved for fairing panels,fuel tanks etc. it is a frame your still painting,right?
anyway, if it IS the frame, or anything else for that matter, wet sand it back.
so, for frame ; wet sand with 12 or 1500. let it dry.
give it a wipe then a quick blast of your lacquer.
let it dry or at least tacky.
then next coat, try and put a thicker coat on this time. you want it to look wet/shiney. but be careful, too much in one go and it will run.
repeat a couple of times and jobs done.
you are NOT finished!
IF it were fairings,fuel tanks etc, ie bigger bits that are seen, then i'd take a bit more care.
once you have built up a few layers of basecoat/colour coat, again wet sand and start clear coating as before, but this time you want to build up the clearcoat, as thick as you want it.(i think the more coats of lacquer,the better it looks when finished)
and once you have a few coats of lacquer on and you are 100% satisfied with it.
consider finishing it off/sealing it.
imho, this makes a HUGE difference.
side by side if you look at 2 panels where 1 has been compounded etc, you will notice the difference, trust me.
For a more professionall loook, consider wet sanding with 2000/2500 then compound, then sealing it with wax or 1 of the other many products available.
theres umpteen guides available, id have a look at a few, if i were you.
Being new to all this, i got some coke cans and prepped them up to match the frame (primer. base coat etc).
When i tried to clear coat, ....something happened, the surface became wrinkly. any idea why (see pic) I don't want this to happen to the frame...
sorry, my pc is f*cked & i cant really see your pics,(also the reason this post looks f*cking terrible, sorry!) but i'd hazard a guess at orange peel effect?
or you are spraying the paint in the wrong settings.
get somewhere dry, very dry so garage or shed might not be suitable at this time of year.
same with temp, you dont want it too warm or the paint will start drying as soon as its left the can.
or your trying to put too much paint on at 1 time?
sorry, but these are just guesses.
try rubbing the offending bits back, then try again. keep practsing till your happy with it.
cheers,
