I had this gnarly crack where two siding panels meet near the back door, and every patch I tried either peeled or were too obvious. Last weekend I got the idea to melt down a scrap piece of siding with a heat gun and work that goo into the crack with a putty knife, then paint over it with a color-matched spray can I got for $9 at the Ace in Toledo. It's been six days now and it actually holds up, you can only see it if you're really looking. Has anyone else tried the heat-gun method, or do you stick to the caulk and touch-up route?
I patched a crack on my buddy's rental siding in Columbus with that mesh tape and flex filler back in 2019. It survived two winters and a hailstorm fine, but last week the whole patch popped out when the temp dropped to 9 degrees. The siding panel itself flexed too much around the edges, so the filler just separated. Is there a trick to keeping patches flexible in extreme cold, or should I have used a heat gun to soften the panel before applying? Has anyone else had a patch fail years later in a deep freeze?
Bought a cedar-toned repair caulk from Home Depot in Columbus last month, patched three nail holes on the south-facing wall, and now those spots are noticeably darker than the panel, did I grab the wrong product or does everyone deal with this shade shift?
A regular on this forum told me to test any caulk color on a hidden spot first, but I went straight to a crack on my front panel at the house in Columbus. Now there's a slightly yellowish strip where I patched it, even though both looked identical in the tube. What do you use to blend in a mismatched patch without redoing the whole repair?
