Trouble With Wheel Paint

[Obey_R 23]

I've just put the last coat of primer on the last speedline and as I was about to flatten it ready for top coat I noticed these imperfections. So I sanded them down thinking it was just normal paint ripples - totally flat and gave them another coat of primer. Then they're back in the same place, deff. isn't damp, can't imagine it would be dust causing it - what could it be?

 

I'm tempted just to top coat over it but I've spent so much time on the wheels I want them to be perfect.

Sorry, I can't help on the subject Ross but assuming the wheels are 1.6 wheels, are you going to polish the centre sections OE style or pain the whole wheel?

[Obey_R 23]

Nope just paint the whole wheel I'm afriad, Jonny - I might consider polishing the centres at some point but I'm on a tight time-scale (and budget) so these will have to do for the time being.

 

This is one with a sinlge top coat..

Looks great Ross, sorry, another tangent but have you had the wheels blasted or just rubbed down?

I need to refurb a set myself.

Looks like the paint has reacted to the wheel to me.. :/

Thats a reaction to something under the paint. Let it dry, sand back and re-do. When you re-apply, lay down a very thin dry dust coat on that area, let that dry off then cover it propley.

 

Simular things can also occur if you heat fresh wet paint to aggressivley. Like with a heat gun.

I'll give it another rub down but I've already tried it once and still came back

 

@ Jonny, I spent what seems like 10 whole years running them down by hand. I bought a back of 20 sheets of 80grit wet and dry and just spend about a month of evenings running them down, then did the backs with a wire brush on a drill. Then went over with 240 and primer, back with 800 wet, top coat - then 1200 wet before another 2 coats, 1200 wet then lacquer.

 

Tha'ts the plan anyway...

 

It's worked out cheap, £3 for the wet and dry, £2.50 per can of primer/top coat/lacquer, used about 4 cans of each. It's just the labour!

You panel wipe them before painting/after keying?

 

Did you sand back to metal?

 

Applying a mist coat before hammering on the primer should stop this re-occuring.
