Paging: S4 Bloom (or anyone else who knows about airbrushing chips)

[SilverTQ]

Ive been searching the forum, and Ive read a few of your posts about airbrushing. Saw a picture of one of your repairs. Looked amazing! I think this is something I could do. You said that you used the Paashe H-Set Single Action. That includes the airbrush, bottle, etc...but what compressor did you use to power it? or did you use something else? (sorry for the n00b question) Also, your link to the Autopia thread on doing airbrush repairs is no longer active. How would you recomend fixing a stone chip? Clean out chip and just spray in the chip, or is it ok to overspray a little? Also, same question goes for applying the clearcoat. If you could help me out that would be great!! TIA

I used my full size Sears air compressor...I just dialed it down to about 40lbs. You can get "canned air" cheaply or special made airbrush compressors which are sort of pricey.

Get a piece of plastic or cardboard index cards and cut a round hole in it much smaller than the chip you are filling. Spray "through" the hole and systematically fill in the chip avoiding overspray as much as possible on the surrounding areas. You don't want build up outside the chip. (but if you can't avoid it it can be removed with a solvent on a Q-Tip or foam swab) The size of the pray pattern that fills your chip is dependant on the size of the hole and how far away you hold the card. It's very controllable.

Airbrush coats are VERY thin. It can take 10-15 coats to bring the chip near level. If you have an area (a visual break, like a seam or crease) where you can spray up to with the clearcoat then overspray the whole area with clear for a more seamless fix.

If your chip is in the middle of a panel (and no good way to start and stop a clearcoat coverage and still keep in discreet) then keep the clearcoat within the chip. Use the index card trick.

Make sense?

I ended up buying the Paasche H-Single action air brush set, an air compressor and regulator. The index card idea sounds like a great trick. Should help prevent overspray. One question though...you wrote in your autopia thread that you mixed the paint 50/50 with laquer thinner. Is this to help the paint flow better through the airbrush? Also, i bought some clear along with my paint from paintscratch.com, should I mix this 50/50 with laquer thinner as well? I assume any laquer thinner would work. Thanks!

Experiment with what works for you, but be consistant with the dilution through the whole process.
