For those of you with allergic reactions to dope and other adhesives, You should be using a respirator anyway. I use dope on full size aircraft and I refuse to even open a can of butyrate or nitrate dope without a respirator. If you have been doping for the last 20 or 30 years without a respirator, the damage to your lungs, liver and kidneys has already been done. A respirator and cartridges are cheap compared to permanent organ damage. Once damaged, you cannot go back. I know this sounds preachy, but if you can smell the product at all, you are doing damage. Sorry if I come off as annoying to anyone.
