AFTER SOME EXPERIMENTATION WITH BUILD SHEETS FROM A LEMANS OR TWO (WORTHLESS AS FAR AS I WAS CONCERNED)THIS IS WHAT I CAME UP WITH.
HERE IS HOW TO GET THE TAR OUT OF YOUR BUILD SHEET. THIS SHOULD BE DONE ON A HOT DAY OUT SIDE.

MATERIALS
1. GET SOME FAST CHEAP LAQUER THINNER. 1 gaL
2. A ROLL OF PAPER TOWELS
3. AN OLD NEWSPAER.

PROCEDURE
1. LAY THE NEWSPAPER DOWN THEN TAKE ABOUT 5-10 PAPERTOWELS AND LAY THEM ON THE NEWSPAPER(IN A STACK)
2. NEXT LAY THE TAR STAINED BUILD SHEET FACE DOWN ON THE PAPERTOWEL STACK.
3. POUR SOME OF THE THINNER IN TO A SMALLER GLASS CONTAINER AND RECAP THE GALLON OF THINNER.
4. DRIBBLE A LITTLE THINNER ON THE BACK OF THE BUILD SHEET IN A CORNER AND TAKE A WAD OF PAPERTOWELS AND BLOT THE BACK.
(THE BLOTTING CAUSES THE PAPER TOWELS UNDER THE BUILD SHEET TO WICK THE TAR OUT WITHOUT DAMAGING THE PRINT)!!!!IF YOU BLOT FROM THE FRONT YOU WILL DAMAGE THE SHEET ALONG WITH THE PRINT!!!!!
TRUST ME I HAVE TRIED IT BOTH WAYS.
AFTER BLOTTING A FEW TIMES POUR A LITTLE MORE THINNER ON AND REPEAT IN THE SAME AREA. NOW PICK UP THE SHEET AND ALLOW THE CORNER TO DRY
...BY THIS TIME YOU SHOULD BEGIN TO SEE THE PAPER OF THE BUILD SHEET BEGIN TO WHITEN.
REPEAT THIS PROCESS UNTIL THE SHEET IS CLEAN...
(WHEN THE PAPER TOWELS ON THE BOTTOM BECOME SOAKED WITH LAQUER THINNER REPLACE THEM WITH NEW ONES.
I USED THIS PROCESS TO REMOVE THE TAR FROM A JUDGE CONV. BUILD SHEET AND A 68 HO GTO BUILD SHEET AS WELL AS 2 LEMANS BUILD SHEETS THAT WERE UNABLE TO BE READ BECAUSE THEY WERE SO BLACKENED WITH TAR.

WORK SLOWLY !!!!
GOOD RESULTS ARE ACHIEVED WITH TIME AND PATIENCE.!!!!

Good Luck with your restoration.
