Any tips on fixing burn thoughs?

Of couse, sanding and buffing I have a couple of very small burn thoughs. One or two to color, one or two to the primer. Very small and I wouldn't think warrented repainting the whole panel. On my mustang I just used an airbrush and that worked pretty good, but sometimes left a ring where the clear didn't blend. Again, this is a solid color so no pearl, candy or metallic to worry about. Oh yea, some of the pieces are about two weeks old and some just a few days (since cleared).

Thanks
 
blending can be a pain in the ass... if u mess up.. and have to redo u could have just shot the panel again... airbrushing a solid can be tough.. because u can see it alot of times the color looks different.

but if u want to blend....

1000 grit primer and area where ur guna base.... sand past a little with 1500 grit.. and finish up with either 2000 or 3000 trizac. blend ur color in the 1000 grit area... now clear... shoot ur first coat over the color... second coat just a little bit further but on the 1500 grit.. last coat mix the clear with 100% reducer... blend that out to the 2000 grit.. keeping the clear thin... after that take blending solvent and use that on the edge..

the area will look died back. so u have to lightly sand it and buff without getting too crazy.. the key is to keep the clear in the sanded surface and keep it off the unsaded. if its kept that way.. u have a chance to match the blend to the finish of the rest of the panel.. if not.. u will burn the edge and it will ghost a line.

the key to buffing is to use a foam pad and buff off the blend.. meanin u keep the buffer going the direction of the blend.. if u go the other way it can or will tear the edge. i finish with 3k grit and work slow while buffing.
 
post up some pics and we can better advise, different areas call for different proceedures, horizontal panels? verticle panels, small panels? large panels? are there areas you can break the paint easily-bodylines? middle of the panel or edge?

There are some important things to remember when doing a successful two stage blend. Control your color overspray-dial the gun down so you can put the material on with good control to blend it out without overspraying past your prepped area. Cleanliness is a must-tack rag it between coats if needed. Have a second gun loaded with straight blending solvent and step your coats of clear out just like Sik recomends, right after spraying the last coat of clear dust the dry edge with blending solvent so it melts-if done properly you won't be able to see the transition. Let the repair cure well before any buffing, ok to sand it lightly to open it up so it breathes but don't rush it or you'll get the ghost ring, a few heat cycles really help.

see this is how much of a pain in the ass it is to do it.. bob picked up were i left off.. alot of shit i didnt post that i just dont think about and do now as habit.

i will also add if its a metallic.. that i will get coverage... then sand metallic with 1500 and get it flat and all the overspray off completely and go back for one last coat and bam less over spray. deff.. have to control ur overspray as bob mentioned.. its a key to keep it small..

i also do these type of blends with an airbrush.. even more a pain in the ass!.
 
Thanks for all the great responses.

No pictures handy, but the more I run this over in my mind, there are a couple that it will be just easier and better to rebase and clear the whole panel (pass door, headlight door). I do have a couple on the main body, but they are in places that not very noticeable and a spot repair will do.

The pass door is the one that really sucks. I had a small hair in the clear right smack in the middle of the door - very visable. I was super careful and sanded very slowy and the hair was breaking apart and comming out. Almost to the last little piece and BAM! breakthrough
