silver base problem

hey guys laid down pro spray opel silver today

blended 1 repair on rear qtr cleared whole lot looks top class


then os rear qtr painted the whole rear qtr and blended into the door ,the blend is 100% but looks like were i had the heater blowing in the booth its blown away the pattern and went slightly like fluttery light dark look
then i cleared it

looks good if i turn the side lights off in the booth and keep the above 1ns on ?

whats my options with this ??

i think i will have to re base and clear but i was thinking to say to my mate leave it for a month let it fully cure then scuff and re shoot ?


thanks

It sounds like you have some "mottling" of the metallic. Letting it "cure" isn't going to make a difference. If you were to sand it and redo it, that is the only way to fix it, IF you can.

Some of todays paints can be pretty hard to spray and getting mottling is pretty much the "nature of the beast". A cheaper line is going to do this more than the top of the line products. Thought many of the top of the line products are still susceptible to mottling.

Back off on the gun, a little more air pressure, not so heavy of an application is one way to help.

my plan was to leave it a month so the solvents could come out and then it wouldnt blister/ react

then 600 the panel and re base ??


thanks for the reply

The ultimate is to sand it with that 600 and then let it set for a day or so, now THAT will allow any solvents to flash off completely. Just don't sand thru into the base, that will create another problem with lifting if the base wasn't catatlysed.

If I'm reading this right, your saying that your heater was blowing air AT the quarter???
If that was the case,then yeah the air flow was redistributing the flake orientation and you have a different reflection of the metallics.
Pro Spray is some good base and I've heard nothing but good about it.
Question is,
How important is the work?
If it's a driver and the owner likely will never notice it. Leave it be.
Otherwise,it's a redo and this time,leave the the heater off while you spray or move it.

Just like you guys drive on the wrong side of the road and the water in your sink flows the wrong direction (and they say watching Bart simpson won't teach you anything), so does your air rotation, due to the coriolis effect. Are you sure you were using a southern hemisphere paint?
Okay being serious now and ribbing scotland aside.
I only used prospray once so far, but it was a silver. But it seemed like a good quality paint with good coverage and good metallic control to me, at half the cost the same color would have been in ppg dbc.
Unfortunatly, if you have blotchy uneven metallic, like brian and mike already mentioned, you will have to sand and reblend your base and then clearcoat if you want to correct. Really Shouldn't take all that much base if your new coat sprays evenly.

yes i usually have the heater pointing in BUT i just bought a new geater and it powerfull fan

so yes its like the gun was fluttering but it was the heater blowing the fan away


sorry but even if it was a blind mans car i would never leave any defects
i have been painting for 4 years now and never done anything like this

its a friend from my work and i realy need to get it right

thanks for the advice

tommy

Silvers can be tough, I would wet sand it with 600 then shoot one coat of intercoat clear over the whole area, then spray your blend again over the intercoat clear and then shoot your topcoat clear. The intercoat provides a nice surface to blend your color into and will let you see what you are doing easier.
