Fish,
I am talking to kenny right now and he said when you block the car get k38 high build primer by ppg and you will need the hardner and the activator.4:1:1 is the formula.He also says to get guid coat in the powder form to block the car correctly for black he said he would block 4-5 times with the last blocking at 600 grit.Do it in the following this is how he does his cars and you have seen them.
blocking-1.
1.80 grit
2.180 grit
3.220 grit
4.400 grit
5.600 grit
And if you want it to be no sand scratches go with 800 or 1000 grit for last block.
Suppplies are going to be expensive but if you want it right then it will cost.He is sorry he cant get to your car right now he is so busy finishing a 65 gto and a 70 chevelle 454 car and he has to get his 68 gto conv done to sell on the net all these have to be done and gone by june we shall see.He is building paint booth in garage in april so he can have less hassles.Email him if you have any other questions.
