I have been restoring antique and vintage vehicles for over 40 years - professionally and as a hobbyist! This caulking was highly recommended to me to caulk mahogany deck veneers. The product was stiff coming out of the tube and IMPOSSIBLE to tool, spread or even out. I used the recommended "Sika-Slip" liquid on the tools and the caulking STILL stuck to the tools yielding a rough, uneven surface. It sticks to everything whether yo want it to or not and it is impossible to get off! I pulled the mask off at 35 minutes and the product had already skinned and left "tails" on the mahogany and caulk lines. And NOTHING will clean that off. The product would NOT clean up with ANY type of reducer - even that made by the company. It just smeared and spread. After 5 days following the two day drying time advertised in the chart, I applied a final top gloss coat of Epiphanes Varnish thinned to spray with the appropriate spray reducer. One week later, the varnish on the mahogany is dry and gorgeous but that on top of the sika flex caulking is still sticky and tacky. I wonder if it is ever going to dry hard or if I'm going to have to strap the entire boat deck and start over. Extremely irritated and DO NOT RECOMMEND this product under ANY CIRCUMSTANCES!
