tack clothes w/Conversion Varnish8/27/19
Never used tack clothes with anything but automotive
Just starting to spray a lot of conversion varnish
Are these ok between coats ?
We don't use tack cloths for fear of contamination. We use microfiber cloths. Last forever and can wash. Combination of air blow off and microfiber works for us.
I know many finishers won't believe this
I've used tack cloths for years on precats, postcats, cv's, and 2k poly and never had an issue.
Tack cloth isn't likely to contaminate anything, the minuscule amount of residue it leaves isn't going to hijack anything.
However, I've sprayed CV since 2004 and never needed a tack cloth. Usually just a good "textured" shop rag will work. Something that has the texture of a bath rag works fantastic in most cases.
I've also had seasons (especially in cool weather when CV cures slower) that a very fine grit sanding sponge was the best--- it easily knocks off small dust fingerprints. In cool weather, the slower curing can result it clumpy, sticky dust.
Agree with Craig M I've been using tack clothes for years with Solvent, water base and even powder coating and never have had an issue.
