sprayed 100 shot on platinums

I wouldnt know for sure, you might have got lucky and the kit might have been jetted back, but I dunno, if everything sounds ok and the cars not running funny or any hicups like that, change the oil and stuff to check it all out, but it might be ok

I believe you answered your own question, follow Blown's advice and do an oil change.

Stick with copper plugs. For now youre okay, but it probably will do some damage later. Copper plug are pretty cheap too take the time and switch to them....

Dont do that again! If it's still running fine, you are probably okay, you would know if you fugged something up. Spraying on platinum plugs dosent mean instant death to the engine, well, not always anyway but it can cause problems, sometimes small problems, sometimes big. It's best to just avoid all of that and not run them.

I remember my Powerdyne car pinging on the way home after I bought it, I popped the hood and tried to look to see what plugs it had, good ole Bosch Platinums. Changed to Autolite 24's and it helped some but didnt fix all of the detonation issues because it had a leaky fuel line to the FMU and needed some tuning on the Optimizer.

Platinums and power adders =
