Title: Can I sand out small spot under 4 couts of T-bird
Post by: Jerry Gille on October 15, 2019, 01:06:38 PM

So I started spraying a bow yesterday and managed to get 4 coats of T-bird on before noticing a small spot on the glass.  I don't exactly know what the spot is but don't think it's a scratch.  I think it's some kind of dust/debris particle that stuck to the bow although I can't feel the spot when I run my finger over it.  The bow is to be donated to an upcoming auction and I really want that spot gone. 

What happens if I sand that spot down?  Will the finish blend well when I start spraying again?

Gloss or satin?

Satin. I planned to put about 4 more light coats on until I found this spot. Don't have time to work on it for a few days but I am really hoping to not have to sand the whole limb side down.

I have blended satin when I dinged limbs with no issues.

For the last coat, I usually back up a foot or two and give the bow a quick light coat. This gives the finish a flatter slightly “frosted” look. This helps hide blemishes. Don’t do more than one coat this way, or the finish will get kinda white looking.

Thanks. I will give it a shot. I guess I don't have anything to lose anyway.

I don't know. I don't tend to follow instructions well. I just kind of do things until I think I am done. I normally spray about 8 thin coats over 2 days.

Yes you can you will just need to sand slowly and do it over a larger area than just where spot is. then blend the Tbird back in.  8 Coats of just satin is a lot you need to be careful that that much satin will not give a off color bluish finish from the flatening agent.  Normally you never need more than 4 coats

I am with Bowman here too many satin coats always give me a Purple Haze. If you need that many coats base coat with gloss then 320 that then a light coat of satin.

I am mostly color blind gentlemen.  I never get "color bluish" or "purple haze."  :)

Thanks for the advice.  I will modify in the future.
