Question: How would you explain the difference between regular Lab-metal and Lab-metal 450?

Lab-metal 450 air dries but then needs to be heat cured prior to sanding and should only be used if for powder coating temps up to 450F.
Question: After filling and air dried, can the hi-temp be sanded smooth before baking?
Answer: Repair needs to be baked first then sanded.
Question: How do I determine the shelf life of Lab metal/ Hi Temp Lab metal
Answer: Lab metal shelf life = 2 years in an unopened can
Hi Temp Lab metal shelf life = 1 year in an unopened can
Batch sticker on top of can = expiration date
Distributors are advised to rotate stock, Lab metal and Hi Temp Lab metal should not contain any lumps (should be like creamy peanut butter) Contact Alvin Products for replacement.
Question: Beware of Negative Reviews
Answer: Alvin Products/Lab metal stands behind Lab metal and Hi Temp Lab metal since 1950. Beware of negative reviews from users who simply did not follow instructions. Solvent evaporation is how Lab metal dries. Heat curing needs to be done with Hi Temp Lab metal. If surface preparation, dry time, re-coat windows, heat curing instructions are not followed, negative results/failures could occur. Please contact Alvin direct prior to each application.
