are there any avalible, any one have success with them i lost 40 psi in a week is that a leak even worth sealing?

ummm if you can find the leak you may be able to pacth it with something, but if not... might just hade to replace something...

Do you know where the leak is?

no idea thats why im wondering if there is a leak detection kit for R12, heard someone mention redtek. and ive found two RE12 sealant products but wonder if they are worth it.

you may have to take it to a AC place if you want to keep the R12, if not get a change over kit and get the Leak detector for the UV light and then do that...

no leak dye that they have is compatable with R12 so they want me to change it over. i want to stay R12. so back on point any leak dectors for R12 systems.

Have you tried ebay. I bought my r12 refil and oil cahrge kit off of ebay. Worked good

cheetah did you have a leak in youir system. did what you buy off ebay have a leak sealant, did it work? brand? ya found maybey one w/ sealant on ebay but have no idea how good it is for my leak, and how bad my leak is if i lost 40psi in a week,or worth trying to seal

Don't use any sealant'*, they do more damage then they are worth. Go buy a R134a kit and some UV dye and convert your car to 134a, or take it to a reputable shop and ask them to find your leak..
