McMillan stock painting issue

[letronshootit]

Hi Guys, I have a used McMillan Tooley stock that has ridden the bags in silicone for 2 years. I have been prepping by sanding and cleaning with Fin-L-Wash from Napa before priming. Primer was rattle-can sealer primer also Napa. All looks good until you throw paint on and you get fish-eyes where the bags contact the stock. I have repeated this process 3x and results the same. My conclusion is silicone in the fibers of stock, I am wiping the stock with the Fin-L-Wash not scrubbing, I was considering trying lacquer thinner and scrubbing. I never had this much trouble painting vehicles but again they aren't silicone worn either. Ideas?

Did you sand completely through the gel-coat? If you have, you can purchase a gel-coat repair kit to cover the exposed glass.

If silicon is present, paint will not stick to it like it should....
A through scrubbing with thinner is called for..

I use rattle can Dupli-color etching primer and paint, They work very well together. You may be getting fish eyes because you waited too long after primer was sprayed on before the pain or visa versa. Or your primer and paint just dont like each other.
I did primer one weekend then paint the next weekend on this one making sure I gave the primer ample amount of time to gas off. Turned out well.

I will scrub the areas where fisheyes happened with thinner and try again. As I mentioned silicone is the culprit and getting rid of it is the problem. Thank you, Ron

Thinner will evaporate to fast. You need a real (wax and grease remover) Use several absorbent paper towels soaking the part
and wiping off with clean towels. Even try heating the part to open the pores and than soaking again. Hot water and ammonia based
cleaner is another method, Followed again with slow dry solvent. Silicate can be a real bitch. Especially if it has worked its way into another finish.

If you find that you just cant get all the silicone out, try a coat or two with a can of shellac to seal it, then primer and paint. Shellac will act as a barrier.
