Few questions I need help *ASAP*

Post by Bradley on November 4th 2010, 5:08 pm

Ok well I usually use mineral spirits in my roller paint jobs, but this time I decided I would try Penatrol... now I have a few questions about penatrol.

1) Is it ok to use Penatrol as a wipedown before painting, like how we use mineral spirits to clean the subject? It seems to be really oily?

2) What is a good mix for paint:penatrol? I have read of a few people using 2:1, but I have done two coats on my mustang and its more orange peel than I would like..I usually do 1:1 with mineral spirits or 50/50.

Now I have a question about rolling, you know how on like horizontal surfaces like the hood, roof, and trunk, why am I getting roller marks and how do I get rid of them? Will they come out in the sanding?

Use something other than mineral spirits to wipe the surface prior to painting, I use alcohol. Mineral spirits will soften the previous coat of paint, and may even lift it.

Can't help with #2, but for the rolling on. If you have it thin enough, and you roll it with a fairly dry roller a few minutes after you lay the coat on, you can remove the paint roller marks, and smooth out the air bubbles.

I use denatured alcohol to wipe down. It's beside paint thinners and other similar materials in hardware stores.
