very cool tip...i bet that saves a lot of headache in finishing..
....Dan, do you think the alcohol has the effect of making it penetrate like xylene or just thin it?
I'm not Dan but...
You're better off not thinning it, adding solvent will lower the viscosity, but it also degrades the resin, physical properties drop when you add anything not in the original formula. Is also does little to help penetration, so you don't really gain much for the downside of weakening the resin. Some people claim adding as much as 50% of some type of solvent works great, but if you’ve ever seen what it does to resin you’d think differently. This applies to both epoxy and polyester. Many of the penetrating epoxies on the market are just normal epoxies with a great deal of low cost solvent added, then they jack up the price.
Thinning reduces the dissolved solids and strength of the resin as much as 35%.
